* Change some of the existing plpgsql regression test cases so that theyTom Lane2004-09-20
| | | | | exercise dollar quoting and named function parameters. AFAICS we had no tests of either feature before.
* Fix some shortcomings in psql's autocommit-off mode concerning detectionTom Lane2004-09-20
| | | | | | | of commands for which a transaction block should not be forced. Recognize VACUUM and other PreventTransactionChain commands; handle nested /* .. */ comments correctly; handle multibyte encodings correctly. Michael Paesold with some kibitzing from Tom Lane.

* Add defenses against plpython functions being declared to take or returnTom Lane2004-09-19
| | | | | pseudotypes. Not sure why I neglected to add these checks at the same time I added them to the other PLs, but it seems I did.
* Fix estimate_num_groups to be able to use expression-index statisticsTom Lane2004-09-18
| | | | when there is an expressional index matching a GROUP BY item.

* Hashed LEFT JOIN would miss outer tuples with no inner match if the joinTom Lane2004-09-17
| | | | | | was large enough to be batched and the tuples fell into a batch where there were no inner tuples at all. Thanks to Xiaoyu Wang for finding a test case that exposed this long-standing bug.
* Now that xmax and cmin are distinct fields again, we should zero xmax whenTom Lane2004-09-17
| | | | | | creating a new tuple. This is just for debugging sanity, though, since nothing should be paying any attention to xmax when the HEAP_XMAX_INVALID bit is set.
* Fix oversight: there's no reason for PG_TRY to use sigsetjmp(buf,1)Tom Lane2004-09-16
| | | | | since we don't change the signal mask during normal backend operations. Use sigsetjmp(buf,0) to avoid many unnecessary kernel calls.
* Remove erroneous Assert, per example from Kris Jurka.Tom Lane2004-09-16

* Add some marginal tweaks to eliminate memory leakages associated withTom Lane2004-09-16
| | | | | subtransactions. Trivial subxacts (such as a plpgsql exception block containing no database access) now demonstrably leak zero bytes.
* RecentXmin is too recent to use as the cutoff point for accessingTom Lane2004-09-16
| | | | | | | pg_subtrans --- what we need is the oldest xmin of any snapshot in use in the current top transaction. Introduce a new variable TransactionXmin to play this role. Fixes intermittent regression failure reported by Neil Conway.
* Restructure subtransaction handling to reduce resource consumption,Tom Lane2004-09-16
| | | | | | | | | | | | | | | | | as per recent discussions. Invent SubTransactionIds that are managed like CommandIds (ie, counter is reset at start of each top transaction), and use these instead of TransactionIds to keep track of subtransaction status in those modules that need it. This means that a subtransaction does not need an XID unless it actually inserts/modifies rows in the database. Accordingly, don't assign it an XID nor take a lock on the XID until it tries to do that. This saves a lot of overhead for subtransactions that are only used for error recovery (eg plpgsql exceptions). Also, arrange to release a subtransaction's XID lock as soon as the subtransaction exits, in both the commit and abort cases. This avoids holding many unique locks after a long series of subtransactions. The price is some additional overhead in XactLockTableWait, but that seems acceptable. Finally, restructure the state machine in xact.c to have a more orthogonal set of states for subtransactions.

* Redesign query-snapshot timing so that volatile functions in READ COMMITTEDTom Lane2004-09-13
| | | | | | | | | | | | | mode see a fresh snapshot for each command in the function, rather than using the latest interactive command's snapshot. Also, suppress fresh snapshots as well as CommandCounterIncrement inside STABLE and IMMUTABLE functions, instead using the snapshot taken for the most closely nested regular query. (This behavior is only sane for read-only functions, so the patch also enforces that such functions contain only SELECT commands.) As per my proposal of 6-Sep-2004; I note that I floated essentially the same proposal on 19-Jun-2002, but that discussion tailed off without any action. Since 8.0 seems like the right place to be taking possibly nontrivial backwards compatibility hits, let's get it done now.

* When LockAcquire fails at the stage of creating a proclock object, beTom Lane2004-09-12
| | | | | sure to clean up the already-created lock object, if it has no other references. Avoids possibly-permanent leak of shared memory.
* Renumber SnapshotNow and the other special snapshot codes so thatTom Lane2004-09-11
| | | | | | | | ((Snapshot) NULL) can no longer be confused with a valid snapshot, as per my recent suggestion. Define a macro InvalidSnapshot for 0. Use InvalidSnapshot instead of SnapshotAny as the do-nothing special case for heap_update and heap_delete crosschecks; this seems a little cleaner even though the behavior is really the same.
* Ensure that pg_largeobject references opened by lo_import() or lo_export()Tom Lane2004-09-11
| | | | | will be cleaned up at end of transaction, even when there is no other LO operation in the transaction. Per bug report from Daniel Schuchardt.
* Fix some problems with restoring databases owned by non-superusers,Tom Lane2004-09-10
| | | | | as per bug #1249; and remove the last vestiges of using \connect to change authorization.
* Fire non-deferred AFTER triggers immediately upon query completion,Tom Lane2004-09-10
| | | | | | | | | | | | | rather than when returning to the idle loop. This makes no particular difference for interactively-issued queries, but it makes a big difference for queries issued within functions: trigger execution now occurs before the calling function is allowed to proceed. This responds to numerous complaints about nonintuitive behavior of foreign key checking, such as http://archives.postgresql.org/pgsql-bugs/2004-09/msg00020.php, and appears to be required by the SQL99 spec. Also take the opportunity to simplify the data structures used for the pending-trigger list, rename them for more clarity, and squeeze out a bit of space.
