* Check for interrupts and stack overflow in TParserGet().Tom Lane2023-06-24
| | | | | | | | | | | | | | | TParserGet() recurses for some token types, meaning it's possible to drive it to stack overflow. Since this is a minority behavior, I chose to add the check_stack_depth() call to the two places that recurse rather than doing it during every single call. While at it, add CHECK_FOR_INTERRUPTS(), because this can run unpleasantly long for long inputs. Per bug #17995 from Zuming Jiang. This is old, so back-patch to all supported branches.

* Fix cache lookup hazards introduced by ff9618e82a.Nathan Bossart2023-06-22
| | | | | | | | | | | | | | | | | | | | | | | | | ff9618e82a introduced has_partition_ancestor_privs(), which is used to check whether a user has MAINTAIN on any partition ancestors. This involves syscache lookups, and presently this function does not take any relation locks, so it is likely subject to the same kind of cache lookup failures that were fixed by 19de0ab23c. To fix this problem, this commit partially reverts ff9618e82a. Specifically, it removes the partition-related changes, including the has_partition_ancestor_privs() function mentioned above. This means that MAINTAIN on a partitioned table is no longer sufficient to perform maintenance commands on its partitions. This is more like how privileges for maintenance commands work on supported versions. Privileges are checked for each partition, so a command that flows down to all partitions might refuse to process them (e.g., if the current user doesn't have MAINTAIN on the partition). In passing, adjust a few related comments and error messages, and add a test for the privilege checks for CLUSTER on a partitioned table.

* nbtree VACUUM: cope with topparent inconsistencies.Peter Geoghegan2023-06-21
| | | | | | | | | | | | | | | | | | Avoid "right sibling %u of block %u is not next child" errors when vacuuming a corrupt nbtree index. Just LOG the issue and press on. That way VACUUM will have a decent chance of finishing off all required processing for the index (and for the table as a whole). This is similar to recent work from commit 5abff197, as well as work from commit 5b861baa (later backpatched as commit 43e409ce), which taught nbtree VACUUM to keep going when its "re-find" check fails. The hardening added by this commit takes place directly after the "re-find" check, right before the critical section for the first stage of page deletion.

* ICU: do not convert locale 'C' to 'en-US-u-va-posix'.Jeff Davis2023-06-21
| | | | | | | | | | | | | | | | | | | | | Older versions of ICU canonicalize "C" to "en-US-u-va-posix"; but starting in ICU version 64, the "C" locale is considered obsolete. Postgres commit ea1db8ae70 introduced code to always canonicalize "C" to "en-US-u-va-posix" for consistency and convenience, but it was deemed too confusing. This commit removes that code, so that "C" is treated like other ICU locale names: canonicalization is attempted, and if it fails, the behavior is controlled by icu_validation_level. A similar change was previously committed as f7faa9976c, then reverted due to an ICU-version-dependent test failure. This commit un-reverts it, omitting the test because we now expect the behavior to depend on the version of ICU being used.

* Avoid Assert failure when processing empty statement in aborted xact.Tom Lane2023-06-21
| | | | | | | | | | | | | | | | | | | | | exec_parse_message() wants to create a cached plan in all cases, including for empty input. The empty-input path does not have a test for being in an aborted transaction, making it possible that plancache.c will fail due to trying to do database lookups even though there's no real work to do. One solution would be to throw an aborted-transaction error in this path too, but it's not entirely clear whether the lack of such an error was intentional or whether some clients might be relying on non-error behavior. Instead, let's hack plancache.c so that it treats empty statements with the same logic it already had for transaction control commands, ensuring that it can soldier through even in an already-aborted transaction. Per bug #17983 from Alexander Lakhin. Back-patch to all supported branches. Discussion: https://postgr.es/m/17983-da4569fcb878672e@postgresql.org

* Disable use of archiving in 009_twophase.plMichael Paquier2023-06-21
| | | | | | | | | | | | | | | | | This partially reverts 68cb5af, as using archiving to enforce the rename of the last partial segment of the old timeline at promotion to use .partial as suffix is impacting the tests when it does switchovers. As showed by the logs gathered by the CI in the tests that failed, a new standby may fail to find the WAL segment it needs to follow a promoted instance with its timeline jump, as it got renamed to .partial. This problem would manifest as a run timeout with 009_twophase.pl, as the new standby repeatedly requests a segment from the promoted primary that it would not find.

* Fix hash join when inner hashkey expressions contain Params.Tom Lane2023-06-20
| | | | | | | | | | | | | | | | | | | | | | | | If the inner-side expressions contain PARAM_EXEC Params, we must re-hash whenever the values of those Params change. The executor mechanism for that exists already, but we failed to invoke it because finalize_plan() neglected to search the Hash.hashkeys field for Params. This allowed a previous scan's hash table to be re-used when it should not be, leading to rows missing from the join's output. (I believe incorrectly-included join rows are impossible however, since checking the real hashclauses would reject false matches.) This bug is very ancient, dating probably to d24d75ff1 of 7.4. Sadly, this simple fix depends on the plan representational changes made by 2abd7ae9b, so it will only work back to v12. I thought about trying to make some kind of hack for v11, but I'm leery of putting code significantly different from what is used in the newer branches into a nearly-EOL branch. Seeing that the bug escaped detection for a full twenty years, problematic cases must be rare; so I don't feel too awful about leaving v11 as-is. Per bug #17985 from Zuming Jiang. Back-patch to v12.

* Fix another cause of "wrong varnullingrels" planner failures.Tom Lane2023-06-20
| | | | | | | | | | | | | | | | | | | I removed the delay_upper_joins mechanism in commit b448f1c8d, reasoning that it was only needed when we have a single-table (SELECT ... WHERE) as the immediate RHS child of a left join, and we could get rid of that by hoisting the WHERE condition into the parent join's quals. However that new code missed a case: we could have "foo LEFT JOIN ((SELECT ... WHERE) LEFT JOIN bar)", and if the two left joins can be commuted then we now have the problematic query shape. We can fix this too easily enough, by allowing the syntactically-lower left join to pass through its parent qual location pointer recursively. That lets prepjointree.c discard the SELECT by temporarily hoisting the WHERE condition into the ancestor join's qual. Per bug #17978 from Zuming Jiang.

* Don't include outer join relids in lateral_relids bitmapsets.Tom Lane2023-06-20
| | | | | | | | | | | | | | This avoids an assertion failure when outer joins are rearranged per identity 3. Listing only the baserels from a PlaceHolderVar's ph_lateral set should be enough to ensure that the required values are available when we need to compute the PHV --- it's what we did before inventing nullingrel sets, after all. It's a bit unsatisfying; but with beta2 hard upon us, there's not time to look for an aesthetically cleaner fix.

* Centralize fixups for mismatched nullingrels in nestloop params.Tom Lane2023-06-20
| | | | | | | | | | | | | | | | | | | | It turns out that the fixes we applied in commits bfd332b3f and 63e4f13d2 were not nearly enough to solve the problem. We'd focused narrowly on subquery RTEs with lateral references, but lateral references can occur in several other RTE kinds such as function RTEs. Putting the same hack into half a dozen code paths seems quite unattractive. Hence, revert the code changes (but not the test cases) from those commits and instead solve it centrally in identify_current_nestloop_params(), as Richard proposed originally. This is a bit annoying because it could mask erroneous nullingrels in nestloop params that are generated from non-LATERAL parameterized paths; but on balance I don't see a better way. Maybe at some future time we'll be motivated to find a more rigorous approach to nestloop params, but that's not happening for beta2.

* fd.c: Retry after EINTR in more placesAndres Freund2023-06-19
| | | | | | | | | | | | | | | | | | | | | | | Starting with 4d330a61bb1 we can use posix_fallocate() to extend files. Unfortunately in some situation, e.g. on tmpfs filesystems, EINTR may be returned. See also 4518c798b2b. To fix, add a retry path to FileFallocate(). In contrast to 4518c798b2b the amount we extend by is limited and the extending may happen at a high frequency, so disabling signals does not appear to be the correct path here. Also add retry paths to other file operations currently lacking them (around fdatasync(), fsync(), ftruncate(), posix_fadvise(), sync_file_range(), truncate()) - they are all documented or have been observed to return EINTR. Even though most of these functions used in the back branches, it does not seem worth the risk to backpatch - outside of the new-to-16 case of posix_fallocate() I am not aware of problem reports due to the lack of retries.

* Don't use partial unique indexes for unique proofs in the plannerDavid Rowley2023-06-19
| | | | | | | | | | | | | | | | | | | Here we adjust relation_has_unique_index_for() so that it no longer makes use of partial unique indexes as uniqueness proofs. It is incorrect to use these as the predicates used by check_index_predicates() to set predOK makes use of not only baserestrictinfo quals as proofs, but also qual from join conditions. For relation_has_unique_index_for()'s case, we need to know the relation is unique for a given set of columns before any joins are evaluated, so if predOK was only set to true due to some join qual, then it's unsafe to use such indexes in relation_has_unique_index_for(). The final plan may not even make use of that index, which could result in reading tuples that are not as unique as the planner previously expected them to be.

* When removing a left join, clean out references in EquivalenceClasses.Tom Lane2023-06-15
| | | | | | | | | | | | | | | | | | | | Since commit b448f1c8d, we've been able to remove left joins (that are otherwise removable) even when they are underneath other left joins, a case that was previously prevented by a delay_upper_joins check. This is a clear improvement, but it has a surprising side-effect: it's now possible that there are EquivalenceClasses whose relid sets mention the removed baserel and/or outer join. If we fail to clean those up, we may drop essential join quals due to not having any join level that appears to satisfy their relid sets. (It's not quite 100% clear that this was impossible before. But the lack of complaints since we added join removal a dozen years ago strongly suggests that it was impossible.)

But it overlooked the possibility of fractional seconds being present, so that cases as simple as to_jsonb(now()) would defeat it. Fix by adding formats that include ".US" to the list in executeDateTimeMethod(). (Note that while this is nominally microseconds, it'll do the right thing for fractions with fewer than six digits.) In passing, re-order the list to restore the datatype ordering specified in its comment. The violation accidentally did not break anything; but the next edit might be less lucky, so add more comments. Per report from Tim Field. Back-patch to v13 where datetime() was added, like the previous patch. Discussion: https://postgr.es/m/014A028B-5CE6-4FDF-AC24-426CA6FC9CEE@mohiohio.com

* Give postgres.exe the icon of other executables.Noah Misch2023-06-12
| | | | | | | | | | | We had left it icon-free since users won't achieve much by opening it from Windows Explorer. Subsequent to that decision, Task Manager started to show the icon. That shifts the balance in favor of attaching the icon, so do so. No back-patch, but make this late addition to v16. Reviewed by Andres Freund and Magnus Hagander.

* Fix "wrong varnullingrels" for subquery nestloop parameters.Tom Lane2023-06-12
| | | | | | | | | | | | | | | If we apply outer join identity 3 when relation C is a subquery having lateral references to relation B, then the lateral references within C continue to bear the original syntactically-correct varnullingrels marks, but that won't match what is available from the outer side of the nestloop. Compensate for that in process_subquery_nestloop_params(). This is a slightly hacky fix, but we certainly don't want to re-plan C in toto for each possible outer join order, so there's not a lot of better alternatives.

* Remove a few unused global variables and declarations.Heikki Linnakangas2023-06-12
| | | | | | | | | | | | | | | | | | | - Commit 3eb77eba5a, which moved the pending ops queue from md.c to sync.c, introduced a duplicate, unused 'pendingOpsCxt' variable. (I'm surprised none of the compilers or static analysis tools have complained about that.) - Commit c2fe139c20 moved the 'synchronize_seqscans' variable and introduced an extern declaration in tableam.h, making the one in guc_tables.c unnecessary. - Commit 6f0cf87872 removed the 'pgstat_temp_directory' GUC, but forgot to remove the corresponding global variable. - Commit 1b4e729eaa removed the 'pg_krb_realm' GUC, and its global variable, but forgot the declaration in auth.h. Spotted all these by reading the code.
* Fix instability in regression test for Parallel Hash Full JoinMichael Paquier2023-06-12
| | | | | | | | | | | | | As reported by buildfarm member conchuela, one of the regression tests added by 558c9d7 is having some ordering issues. This commit adds an ORDER BY clause to make the output more stable for the problematic query. Fix suggested by Tom Lane. The plan of the query updated still uses a parallel hash full join.

* nbtree: Allocate new pages in separate function.Peter Geoghegan2023-06-10
| | | | | | | | | | | | | | | | | | | | | | | | Split nbtree's _bt_getbuf function is two: code that read locks or write locks existing pages remains in _bt_getbuf, while code that deals with allocating new pages is moved to a new, dedicated function called _bt_allocbuf. This simplifies most _bt_getbuf callers, since it is no longer necessary for them to pass a heaprel argument. Many of the changes to nbtree from commit 61b313e4 can be reverted. This minimizes the divergence between HEAD/PostgreSQL 16 and earlier release branches. _bt_allocbuf replaces the previous nbtree idiom of passing P_NEW to _bt_getbuf. There are only 3 affected call sites, all of which continue to pass a heaprel for recovery conflict purposes. Note that nbtree's use of P_NEW was superficial; nbtree never actually relied on the P_NEW code paths in bufmgr.c, so this change is strictly mechanical. GiST already took the same approach; it has a dedicated function for allocating new pages called gistNewBuffer(). That factor allowed commit 61b313e4 to make much more targeted changes to GiST.

* meson: Add dependencies to perl modules to various script invocationsAndres Freund2023-06-09
| | | | | | | | | | | Eventually it is likely worth trying to deal with this in a more expansive way, by generating dependency files generated within the scripts. But it's not entirely obvious how to do that in perl and is work more suitable for 17 anyway.
