Tom Lane	5bab36e9f6	Revise executor APIs so that all per-query state structure is built in ... a per-query memory context created by CreateExecutorState --- and destroyed by FreeExecutorState. This provides a final solution to the longstanding problem of memory leaked by various ExecEndNode calls.	23 years ago
Tom Lane	1fd0c59e25	Phase 1 of read-only-plans project: cause executor state nodes to point ... to plan nodes, not vice-versa. All executor state nodes now inherit from struct PlanState. Copying of plan trees has been simplified by not storing a list of SubPlans in Plan nodes (eliminating duplicate links). The executor still needs such a list, but it can build it during ExecutorStart since it has to scan the plan tree anyway. No initdb forced since no stored-on-disk structures changed, but you will need a full recompile because of node-numbering changes.	23 years ago

Bruce Momjian	623bf843d2	Change Copyright from PostgreSQL, Inc to PostgreSQL Global Development Group.	25 years ago
Tom Lane	badce86a2c	First stage of reclaiming memory in executor by resetting short-term ... memory contexts. Currently, only leaks in expressions executed as quals or projections are handled. Clean up some old dead cruft in executor while at it --- unused fields in state nodes, that sort of thing.	26 years ago
Bruce Momjian	a12a23f0d0	Remove unused include files. Do not touch /port or includes used by defines.	26 years ago
Bruce Momjian	52f77df613	Ye-old pgindent run. Same 4-space tabs.	26 years ago
Tom Lane	dd979f66be	Redesign DISTINCT ON as discussed in pgsql-sql 1/25/00: syntax is now ... SELECT DISTINCT ON (expr [, expr ...]) targetlist ... and there is a check to make sure that the user didn't specify an ORDER BY that's incompatible with the DISTINCT operation. Reimplement nodeUnique and nodeGroup to use the proper datatype-specific equality function for each column being compared --- they used to do bitwise comparisons or convert the data to text strings and strcmp(). (To add insult to injury, they'd look up the conversion functions once for each tuple...) Parse/plan representation of DISTINCT is now a list of SortClause nodes. initdb forced by querytree change...	26 years ago
Bruce Momjian	5c25d60244	Add: ... * Portions Copyright (c) 1996-2000, PostgreSQL, Inc to all files copyright Regents of Berkeley. Man, that's a lot of files.	26 years ago
Bruce Momjian	86ef36c907	New NameStr macro to convert Name to Str. No need for var.data anymore. ... Fewer calls to nameout. Better use of RelationGetRelationName.	26 years ago
Bruce Momjian	3406901a29	Move some system includes into c.h, and remove duplicates.	27 years ago

Tom Lane	d03e98737c	Replace typtoout() and gettypelem() with a single routine, ... so that fetching an attribute value needs only one SearchSysCacheTuple call instead of two redundant searches. This speeds up a large SELECT by about ten percent, and probably will help GROUP BY and SELECT DISTINCT too.	27 years ago
Vadim B. Mikheev	6beba218d7	New HeapTuple structure/interface.	27 years ago
Bruce Momjian	a32450a585	pgindent run before 6.3 release, with Thomas' requested changes.	28 years ago
