Tom Lane	53e757689c	Make NestLoop plan nodes pass outer-relation variables into their inner ... relation using the general PARAM_EXEC executor parameter mechanism, rather than the ad-hoc kluge of passing the outer tuple down through ExecReScan. The previous method was hard to understand and could never be extended to handle parameters coming from multiple join levels. This patch doesn't change the set of possible plans nor have any significant performance effect, but it's necessary infrastructure for future generalization of the concept of an inner indexscan plan. ExecReScan's second parameter is now unused, so it's removed.	16 years ago

Tom Lane	24ee8af573	Rework temp_tablespaces patch so that temp tablespaces are assigned separately ... for each temp file, rather than once per sort or hashjoin; this allows spreading the data of a large sort or join across multiple tablespaces. (I remain dubious that this will make any difference in practice, but certain people insisted.) Arrange to cache the results of parsing the GUC variable instead of recomputing from scratch on every demand, and push usage of the cache down to the bottommost fd.c level.	19 years ago
Tom Lane	acfce502ba	Create a GUC parameter temp_tablespaces that allows selection of the ... tablespace(s) in which to store temp tables and temporary files. This is a list to allow spreading the load across multiple tablespaces (a random list element is chosen each time a temp object is to be created). Temp files are not stored in per-database pgsql_tmp/ directories anymore, but per-tablespace directories. Jaime Casanova and Albert Cervera, with review by Bernd Helmle and Tom Lane.	19 years ago

Tom Lane	69d0a15e2a	Convert hash join code to use MinimalTuple format in tuple hash table ... and batch files. Should reduce memory and I/O demands for such joins.	20 years ago
Bruce Momjian	f2f5b05655	Update copyright for 2006. Update scripts.	20 years ago
Tom Lane	2c0ef9777c	Extend the ExecInitNode API so that plan nodes receive a set of flag ... bits indicating which optional capabilities can actually be exercised at runtime. This will allow Sort and Material nodes, and perhaps later other nodes, to avoid unnecessary overhead in common cases. This commit just adds the infrastructure and arranges to pass the correct flag values down to plan nodes; none of the actual optimizations are here yet. I'm committing this separately in case anyone wants to measure the added overhead. (It should be negligible.) Simon Riggs and Tom Lane	20 years ago
Bruce Momjian	1dc3498251	Standard pgindent run for 8.1.	21 years ago
Tom Lane	849074f9ae	Revise hash join code so that we can increase the number of batches ... on-the-fly, and thereby avoid blowing out memory when the planner has underestimated the hash table size. Hash join will now obey the work_mem limit with some faithfulness. Per my recent proposal (hash aggregate part isn't done yet though).	21 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	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
Tom Lane	db3c4c3a2d	Split 'BufFile' routines out of fd.c into a new module, buffile.c. Extend ... BufFile so that it handles multi-segment temporary files transparently. This allows sorts and hashes to work with data exceeding 2Gig (or whatever the local limit on file size is). Change psort.c to use relative seeks instead of absolute seeks for backwards scanning, so that it won't fail when the data volume exceeds 2Gig.	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
