Bruce Momjian	089003fb46	pgindent run.	23 years ago
Tom Lane	bff0422b6c	Revise hash join and hash aggregation code to use the same datatype- ... 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.	23 years ago
Tom Lane	1afac12910	Create a new file executor/execGrouping.c to centralize utility routines ... shared by nodeGroup, nodeAgg, and soon nodeSubplan.	23 years ago
Tom Lane	a0fa0117a5	Better solution to integer overflow problem in hash batch-number ... 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.	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
Tom Lane	ddb2d78de0	Upgrade planner and executor to allow multiple hash keys for a hash join, ... 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.	23 years ago
Tom Lane	2103b7baa2	Phase 2 of hashed-aggregation project. nodeAgg.c now knows how to do ... hashed aggregation, but there's not yet planner support for it.	23 years ago
Bruce Momjian	d84fe82230	Update copyright to 2002.	24 years ago
Bruce Momjian	ea08e6cd55	New pgindent run with fixes suggested by Tom. Patch manually reviewed, ... initdb/regression tests pass.	24 years ago
Bruce Momjian	6783b2372e	Another pgindent run. Fixes enum indenting, and improves #endif ... spacing. Also adds space for one-line comments.	25 years ago
Bruce Momjian	b81844b173	pgindent run on all C files. Java run to follow. initdb/regression ... tests pass.	25 years ago
Tom Lane	01a819abe3	Make planner compute the number of hash buckets the same way that ... nodeHash.c will compute it (by sharing code).	25 years ago
Bruce Momjian	9e1552607a	pgindent run. Make it all clean.	25 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
Tom Lane	25442d8d2f	Correct oversight in hashjoin cost estimation: nodeHash sizes its hash ... 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.	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	4b2c2850bf	Clean up #include in /include directory. Add scripts for checking includes.	27 years ago
Bruce Momjian	07842084fe	pgindent run over code.	27 years ago
Tom Lane	26069a58e8	Rewrite hash join to use simple linked lists instead of a ... 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.	27 years ago
Bruce Momjian	6724a50787	Change my-function-name-- to my_function_name, and optimizer renames.	27 years ago
