* Add macros for looping through a List without a ListCell.Nathan Bossart2024-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many foreach loops only use the ListCell pointer to retrieve the content of the cell, like so: ListCell *lc; foreach(lc, mylist) { int myint = lfirst_int(lc); ... } This commit adds a few convenience macros that automatically declare the loop variable and retrieve the current cell's contents. This allows us to rewrite the previous loop like this: foreach_int(myint, mylist) { ... } This commit also adjusts a few existing loops in order to add coverage for the new/adjusted macros. There is presently no plan to bulk update all foreach loops, as that could introduce a significant amount of back-patching pain. Instead, these macros are primarily intended for use in new code.

* ALTER TABLE command to change generation expressionPeter Eisentraut2024-01-04
| | | | | | | | | | | | | | | | | | | This adds a new ALTER TABLE subcommand ALTER COLUMN ... SET EXPRESSION that changes the generation expression of a generated column. The syntax is not standard but was adapted from other SQL implementations. This command causes a table rewrite, using the usual ALTER TABLE mechanisms. The implementation is similar to and makes use of some of the infrastructure of the SET DATA TYPE subcommand (for example, rebuilding constraints and indexes afterwards). The new command requires a new pass in AlterTablePass, and the ADD COLUMN pass had to be moved earlier so that combinations of ADD COLUMN and SET EXPRESSION can work.

* Fix use of incorrect TupleTableSlot in DISTINCT aggregatesDavid Rowley2024-01-04
| | | | | | | | | | | | | | | | | | | | | | 1349d2790 added code to allow DISTINCT and ORDER BY aggregates to work more efficiently by using presorted input. That commit added some code that made use of the AggState's tmpcontext and adjusted the ecxt_outertuple and ecxt_innertuple slots before checking if the current row is distinct from the previously seen row. That code forgot to set the TupleTableSlots back to what they were originally, which could result in errors such as: ERROR: attribute 1 of type record has wrong type This only affects aggregate functions which have multiple arguments when DISTINCT is used. For example: string_agg(DISTINCT col, ', ') Thanks to Tom Lane for identifying the breaking commit.

* Track conflict_reason in pg_replication_slots.Amit Kapila2024-01-04
| | | | | | | | | | | | | | | | | | | | | This patch changes the existing 'conflicting' field to 'conflict_reason' in pg_replication_slots. This new field indicates the reason for the logical slot's conflict with recovery. It is always NULL for physical slots, as well as for logical slots which are not invalidated. The non-NULL values indicate that the slot is marked as invalidated. Possible values are: wal_removed = required WAL has been removed. rows_removed = required rows have been removed. wal_level_insufficient = the primary doesn't have a wal_level sufficient to perform logical decoding. The existing users of 'conflicting' column can get the same answer by using 'conflict_reason' IS NOT NULL.

* Avoid masking EOF (no-password-supplied) conditions in auth.c.Tom Lane2024-01-03
| | | | | | | | | | | | | | | CheckPWChallengeAuth() would return STATUS_ERROR if the user does not exist or has no password assigned, even if the client disconnected without responding to the password challenge (as libpq often will, for example). We should return STATUS_EOF in that case, and the lower-level functions do, but this code level got it wrong since the refactoring done in 7ac955b34. This breaks the intent of not logging anything for EOF cases (cf. comments in auth_failed()) and might also confuse users of ClientAuthentication_hook. Per report from Liu Lang.

* Allow upgrades to preserve the full subscription's state.Amit Kapila2024-01-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This feature will allow us to replicate the changes on subscriber nodes after the upgrade. Previously, only the subscription metadata information was preserved. Without the list of relations and their state, it's not possible to re-enable the subscriptions without missing some records as the list of relations can only be refreshed after enabling the subscription (and therefore starting the apply worker). Even if we added a way to refresh the subscription while enabling a publication, we still wouldn't know which relations are new on the publication side, and therefore should be fully synced, and which shouldn't. To preserve the subscription relations, this patch teaches pg_dump to restore the content of pg_subscription_rel from the old cluster by using binary_upgrade_add_sub_rel_state SQL function. This is supported only in binary upgrade mode. The subscription's replication origin is needed to ensure that we don't replicate anything twice. To preserve the replication origins, this patch teaches pg_dump to update the replication origin along with creating a subscription by using binary_upgrade_replorigin_advance SQL function to restore the underlying replication origin remote LSN. This is supported only in binary upgrade mode. pg_upgrade will check that all the subscription relations are in 'i' (init) or in 'r' (ready) state and will error out if that's not the case, logging the reason for the failure. This helps to avoid the risk of any dangling slot or origin after the upgrade.

* Fix parallel BRIN builds with synchronized scansTomas Vondra2023-12-30
| | | | | | | | | | | | | | | | | | The brinbuildCallbackParallel callback used by parallel BRIN builds did not consider that the parallel table scans may be synchronized, starting from an arbitrary block and then wrap around. If this happened and the scan actually did wrap around, tuples from the beginning of the table were added to the last range produced by the same worker. The index would be missing range at the beginning of the table, while the last range would be too wide. This would not produce incorrect query results, but it'd be less efficient. Fixed by checking for both past and future ranges in the callback. The worker may produce multiple summaries for the same page range, but the leader will merge them as if the summaries came from different workers.

* Minor cleanup of the BRIN parallel build codeTomas Vondra2023-12-30
| | | | | | | | | | | | | | | | | | | Commit b437571714 added support for parallel builds for BRIN indexes, using code similar to BTREE parallel builds, and also a new tuplesort variant. This commit simplifies the new code in two ways: * The "spool" grouping tuplesort and the heap/index is not necessary. The heap/index are available as separate arguments, causing confusion. So remove the spool, and use the tuplesort directly. * The new tuplesort variant does not need the heap/index, as it sorts simply by the range block number, without accessing the tuple data. So simplify that too. Initial report and patch by Ranier Vilela, further cleanup by me.

* Add GUC backtrace_on_internal_errorPeter Eisentraut2023-12-30
| | | | | | | | | | | | | | | When enabled (default off), this logs a backtrace anytime elog() or an equivalent ereport() for internal errors is called. This is not well covered by the existing backtrace_functions, because there are many equally-worded low-level errors in many functions. And if you find out where the error is, then you need to manually rewrite the elog() to ereport() to attach the errbacktrace(), which is annoying. Having a backtrace automatically on every elog() call could be very helpful during development for various kinds of common errors from palloc, syscache, node support, etc. Discussion: https://www.postgresql.org/message-id/flat/ba76c6bc-f03f-4285-bf16-47759cfcab9e@eisentraut.org

* Make all Perl warnings fatalPeter Eisentraut2023-12-29
| | | | | | | | | | | | | | | | | | | | | | | | There are a lot of Perl scripts in the tree, mostly code generation and TAP tests. Occasionally, these scripts produce warnings. These are probably always mistakes on the developer side (true positives). Typical examples are warnings from genbki.pl or related when you make a mess in the catalog files during development, or warnings from tests when they massage a config file that looks different on different hosts, or mistakes during merges (e.g., duplicate subroutine definitions), or just mistakes that weren't noticed because there is a lot of output in a verbose build. This changes all warnings into fatal errors, by replacing use warnings; by use warnings FATAL => 'all'; in all Perl files.

* Improve the implementation of information_schema._pg_expandarray().Tom Lane2023-12-27
| | | | | | | | | | | | | | | | | | | | | This function was originally coded with a handmade expansion of the array subscripts. We can do it a little faster and far more legibly today, by using unnest() WITH ORDINALITY. While at it, let's apply the rowcount estimation support that exists for the underlying unnest() function: reduce the default ROWS estimate to 100 and attach array_unnest_support. I'm not sure that array_unnest_support can do anything useful today with the call sites that exist in information_schema, but it can't hurt, and the existing default rowcount of 1000 is surely much too high for any of these cases. The psql.sql regression script is using _pg_expandarray() as a test case for \sf+. While we could keep doing so, the new one-line function body makes a poor test case for \sf+ row-numbering, so switch it to print another information_schema function.

However, the callers are passing struct stat's st_mtime field which is plain time_t, and add_file_to_manifest itself is passing the value to gmtime(3) which expects plain time_t, so the whole thing would not work at all on any platform where those types are different.

* Fix incorrect data type choices in some read and write calls.Tom Lane2023-12-27
| | | | | | | | | | | | | | | | | | | | | | | | Recently-introduced code in reconstruct.c was using "unsigned" to store the result of read(), pg_pread(), or write(). This is completely bogus: it breaks subsequent tests for the result being negative, as we're being reminded of by a chorus of buildfarm warnings. Switch to "int" as was doubtless intended. (There are several other uses of "unsigned" in this file that also look poorly chosen to me, but for now I'm just trying to clean up the buildfarm.) A larger problem is that "int" is not necessarily wide enough to hold the result: per POSIX, all these functions return ssize_t. In places where the requested read or write length clearly fits in int, that's academic. It may be academic anyway as long as we constrain individual data files to 1GB, since even a readv or writev-like operation would then not be responsible for transferring more than 1GB. Nonetheless it seems like trouble waiting to happen, so I made a pass over readv and writev calls and fixed the result variables where that seemed appropriate. We might want to think about changing some of the fd.c functions to return ssize_t too, for future-proofing; but I didn't tackle that here.

* Improvements and fixes for e0b1ee17dcAlexander Korotkov2023-12-27
| | | | | | | | | | | | | | | | | | | | | | e0b1ee17dc introduced optimization for matching B-tree scan keys required for the directional scan. However, it incorrectly assumed that all keys required for opposite direction scan are satisfied by _bt_first(). It has been illustrated that with multiple scan keys over the same column, a lesser one (according to the scan direction) could win leaving the other one unsatisfied. Instead of relying on _bt_first() this commit introduces code that memorizes whether there was at least one match on the page. If that's true we know that keys required for opposite-direction scan are satisfied as soon as corresponding values are not NULLs. Also, this commit simplifies the description for the optimization of keys required for the current direction scan. Now the flag used for this is named continuescanPrechecked and means exactly that *continuescan flag is known to be true for the last item on the page.
