2003-06-22	Revise hash join and hash aggregation code to use the same datatype-	Tom Lane
	specific hash functions used by hash indexes, rather than the old not-datatype-aware ComputeHashFunc routine. This makes it safe to do hash joining on several datatypes that previously couldn't use hashing. The sets of datatypes that are hash indexable and hash joinable are now exactly the same, whereas before each had some that weren't in the other.
2003-01-10	Create a new file executor/execGrouping.c to centralize utility routines	Tom Lane
	shared by nodeGroup, nodeAgg, and soon nodeSubplan.
2002-12-30	Better solution to integer overflow problem in hash batch-number	Tom Lane
	computation: reduce the bucket number mod nbatch. This changes the association between original bucket numbers and batches, but that doesn't matter. Minor other cleanups in hashjoin code to help centralize decisions.
2002-12-05	Phase 1 of read-only-plans project: cause executor state nodes to point	Tom Lane
	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.
2002-11-30	Upgrade planner and executor to allow multiple hash keys for a hash join,	Tom Lane
	instead of only one. This should speed up planning (only one hash path to consider for a given pair of relations) as well as allow more effective hashing, when there are multiple hashable joinclauses.
2002-11-06	Phase 2 of hashed-aggregation project. nodeAgg.c now knows how to do	Tom Lane
	hashed aggregation, but there's not yet planner support for it.
2002-06-20	Update copyright to 2002.	Bruce Momjian

2001-11-05	New pgindent run with fixes suggested by Tom. Patch manually reviewed,	Bruce Momjian
	initdb/regression tests pass.
2001-10-28	Another pgindent run. Fixes enum indenting, and improves #endif	Bruce Momjian
	spacing. Also adds space for one-line comments.
2001-10-25	pgindent run on all C files. Java run to follow. initdb/regression	Bruce Momjian
	tests pass.
2001-06-11	Make planner compute the number of hash buckets the same way that	Tom Lane
	nodeHash.c will compute it (by sharing code).
2001-03-22	pgindent run. Make it all clean.	Bruce Momjian

2001-01-24	Change Copyright from PostgreSQL, Inc to PostgreSQL Global Development Group.	Bruce Momjian

2000-07-12	First stage of reclaiming memory in executor by resetting short-term	Tom Lane
	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.
2000-04-18	Correct oversight in hashjoin cost estimation: nodeHash sizes its hash	Tom Lane
	table for an average of NTUP_PER_BUCKET tuples/bucket, but cost_hashjoin was assuming a target load of one tuple/bucket. This was causing a noticeable underestimate of hashjoin costs.
2000-01-26	Add:	Bruce Momjian
	* Portions Copyright (c) 1996-2000, PostgreSQL, Inc to all files copyright Regents of Berkeley. Man, that's a lot of files.
1999-07-15	Clean up #include in /include directory. Add scripts for checking includes.	Bruce Momjian

1999-05-25	pgindent run over code.	Bruce Momjian

1999-05-18	Rewrite hash join to use simple linked lists instead of a	Tom Lane
	fixed-size hashtable. This should prevent 'hashtable out of memory' errors, unless you really do run out of memory. Note: target size for hashtable is now taken from -S postmaster switch, not -B, since it is local memory in the backend rather than shared memory.
1999-02-13	Change my-function-name-- to my_function_name, and optimizer renames.	Bruce Momjian

1998-09-01	OK, folks, here is the pgindent output.	Bruce Momjian

1998-02-26	pgindent run before 6.3 release, with Thomas' requested changes.	Bruce Momjian

1998-02-13	Subselects...	Vadim B. Mikheev

1998-01-24	Fix prototypes so they don't look like function definitions.	Bruce Momjian

1997-11-26	Cleanup up include files.	Bruce Momjian

1997-09-08	Used modified version of indent that understands over 100 typedefs.	Bruce Momjian

1997-09-08	Another PGINDENT run that changes variable indenting and case label ↵	Bruce Momjian
	indenting. Also static variable indenting.
1997-09-07	Massive commit to run PGINDENT on all .c and .h files.	Bruce Momjian

1997-08-19	Make functions static where possible, enclose unused functions in #ifdef ↵	Bruce Momjian
	NOT_USED.
1996-08-28	Clean up th ecompile process by centralizing the include files	Marc G. Fournier
	- code compile tested, but due to a yet unresolved problem with parse.h's creation, compile not completed...
