Neil Conway	3df9abd1a5	ALTER TABLE ADD COLUMN exhibits a significant memory leak when adding a ... 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.	21 years ago

Tom Lane	2a6c032503	Repair CLUSTER failure after ALTER TABLE SET WITHOUT OIDS. Turns out ... 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.	21 years ago

Tom Lane	12179c99b1	Marginal hack to merge adjacent ReleaseBuffer/ReadBuffer calls into ... ReleaseAndReadBuffer during GIST index searches. We already did this in btree and rtree, might as well do it here too.	21 years ago

Tom Lane	ee467c3530	Fix minor thinko in logic to set dump order when dumping from a pre-7.3 ... database: aggregates should be dumped in the same pass as operators, not in the same pass as functions.	21 years ago
Tom Lane	cc4f58f4cd	Ensure that all details of the ARC algorithm are hidden within freelist.c. ... This refactoring does not change any algorithms or data structures, just remove visibility of the ARC datastructures from other source files.	21 years ago

Tom Lane	fffb5819ca	Adjust constant-folding of CASE expressions so that the simple comparison ... 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.	21 years ago
