* New arrangement to always let the bgwriter do checkpoints brokeTom Lane2005-02-19
| | | | | CHECKPOINT and some other commands in the context of a standalone backend. Allow a standalone backend to do its own checkpoints.

* Fix SPI cursor support to allow scanning the results of utility commandsTom Lane2005-02-10
| | | | | | that return tuples (such as EXPLAIN). Per gripe from Michael Fuhr. Side effect: fix an old bug that unintentionally disabled backward scans for all SPI-created cursors.

* ALTER TABLE ADD COLUMN exhibits a significant memory leak when adding aNeil Conway2005-02-09
| | | | | | | | | | | | | | | | | | | | column with a default expression. In that situation, we need to rewrite the heap relation. To evaluate the new default expression, we use ExecEvalExpr(); however, this can allocate memory in the current memory context, and ATRewriteTable() does not switch out of the active portal's heap memory context. The end result is a rather large memory leak (on the order of gigabytes for a reasonably sized table). This patch changes ATRewriteTable() to switch to the per-tuple memory context before beginning the per-tuple loop. It also removes an explicit heap_freetuple() in the loop, since that is no longer needed. In an unrelated change, I noticed the code was scanning through the attributes of the new tuple descriptor for each tuple of the old table. I changed this to use precomputation, which should slightly speed up the loop. Thanks to steve@deefs.net for reporting the leak.

* If we're gonna check for array overrun, we really should do so beforeTom Lane2005-02-08
| | | | overrunning the array, not after.
* Prevent 4 more buffer overruns in the PL/PgSQL parser. This is just aNeil Conway2005-02-07
| | | | | minimally-invasive fix for stable branches; a cleaner fix will be committed to HEAD soon.
* Repair CLUSTER failure after ALTER TABLE SET WITHOUT OIDS. Turns outTom Lane2005-02-06
| | | | | | | there are corner cases involving dropping toasted columns in which the previous coding would fail, too: the new version of the table might not have any TOAST table, but we'd still propagate possibly-wide values of dropped columns forward.
* Fix minor thinko in logic to set dump order when dumping from a pre-7.3Tom Lane2005-02-03
| | | | | database: aggregates should be dumped in the same pass as operators, not in the same pass as functions.
* Ensure that all details of the ARC algorithm are hidden within freelist.c.Tom Lane2005-02-03
| | | | | This refactoring does not change any algorithms or data structures, just remove visibility of the ARC datastructures from other source files.
* Improve performance of fmgr.c calling routines for cases with more thanTom Lane2005-02-02
| | | | two arguments. Per suggestions from A. Ogawa.
* Adjust constant-folding of CASE expressions so that the simple comparisonTom Lane2005-02-02
| | | | | | | | form of CASE (eg, CASE 0 WHEN 1 THEN ...) can be constant-folded as it was in 7.4. Also, avoid constant-folding result expressions that are certainly unreachable --- the former coding was a bit cavalier about this and could generate unexpected results for all-constant CASE expressions. Add regression test cases. Per report from Vlad Marchenko.
* Fix a bug induced by the list-rewrite that resulted in incrementing theNeil Conway2005-02-01
| | | | command counter more than necessary. Per report from Michael Fuhr.
* Adjust estimate_num_groups() to not clamp per-relation group countTom Lane2005-02-01
| | | | | | | estimate to less than the number of values estimated for any one grouping Var, as suggested by Manfred. This is intuitively right, and what's more it puts the plan choices in the subselect regression test back the way they were before ...
* Adjust plpgsql to allow assignment to an element of an array that isTom Lane2005-02-01
| | | | | | initially NULL. For 8.0 we changed the main executor to have this behavior in an UPDATE of an array column, but plpgsql's equivalent case was overlooked. Per report from Sven Willenberger.

* When dealing with multiple grouping columns coming from the same table,Tom Lane2005-01-28
| | | | | | | | | clamp the estimated number of groups to table row count over 10, instead of table row count; this reflects a heuristic that people probably won't group over a near-unique set of columns, and the knowledge that we don't currently have any way to estimate the correlation of the columns better than guessing. This change creates a trivial plan change in one of the regression tests.
* Improve planner's estimation of the space needed for HashAgg plans:Tom Lane2005-01-28
| | | | | | look at the actual aggregate transition datatypes and the actual overhead needed by nodeAgg.c, instead of using pessimistic round numbers. Per a discussion with Michael Tiemann.

* Close all cursors created during a failed subtransaction. This is neededTom Lane2005-01-26
| | | | | | to avoid problems when a cursor depends on objects created or changed in the same subtransaction. We'd like to do better someday, but this seems the only workable answer for 8.0.1.

* On Windows, set the postmaster executable's stack size to 4MB, so thatTom Lane2005-01-26

* Minor tweak to avoid unnecessary memory bloat when dumping extremely wideTom Lane2005-01-26
| | | | | | column values in -d mode. Per report from Marty Scholes. This doesn't completely solve the issue, because we still need multiple copies of the field value, but at least one copy can be got rid of painlessly ...

* pg_dump dumped the wrong tablespace for an index (ie, the parent table'sTom Lane2005-01-23
