Tom Lane	a874fe7b4c	Refactor the executor's API to support data-modifying CTEs better. The originally committed patch for modifying CTEs didn't interact well with EXPLAIN, as noted by myself, and also had corner-case problems with triggers, as noted by Dean Rasheed. Those problems show it is really not practical for ExecutorEnd to call any user-defined code; so split the cleanup duties out into a new function ExecutorFinish, which must be called between the last ExecutorRun call and ExecutorEnd. Some Asserts have been added to these functions to help verify correct usage. It is no longer necessary for callers of the executor to call AfterTriggerBeginQuery/AfterTriggerEndQuery for themselves, as this is now done by ExecutorStart/ExecutorFinish respectively. If you really need to suppress that and do it for yourself, pass EXEC_FLAG_SKIP_TRIGGERS to ExecutorStart. Also, refactor portal commit processing to allow for the possibility that PortalDrop will invoke user-defined code. I think this is not actually necessary just yet, since the portal-execution-strategy logic forces any non-pure-SELECT query to be run to completion before we will consider committing. But it seems like good future-proofing.	15 years ago
Tom Lane	629b3af27d	Convert contrib modules to use the extension facility. This isn't fully tested as yet, in particular I'm not sure that the "foo--unpackaged--1.0.sql" scripts are OK. But it's time to get some buildfarm cycles on it. sepgsql is not converted to an extension, mainly because it seems to require a very nonstandard installation process.

Tom Lane	77acab75df	Modify ShmemInitStruct and ShmemInitHash to throw errors internally, rather than returning NULL for some-but-not-all failures as they used to. Remove now-redundant tests for NULL from call sites. We had to do something about this because many call sites were failing to check for NULL; and changing it like this seems a lot more useful and mistake-proof than adding checks to the call sites without them.	16 years ago

Itagaki Takahiro	8964dbd51e	Add buffer access counters to pg_stat_statements. This uses the same infrastructure with EXPLAIN BUFFERS to support {shared\|local}_blks_{hit\|read\|written} andtemp_blks_{read\|written} columns in the pg_stat_statements view. The dumped file format also updated. Thanks to Robert Haas for the review.	16 years ago

Heikki Linnakangas	84d723b6ce	Previous fix for temporary file management broke returning a set from PL/pgSQL function within an exception handler. Make sure we use the right resource owner when we create the tuplestore to hold returned tuples. Simplify tuplestore API so that the caller doesn't need to be in the right memory context when calling tuplestore_put* functions. tuplestore.c automatically switches to the memory context used when the tuplestore was created. Tuplesort was already modified like this earlier. This patch also removes the now useless MemoryContextSwitch calls from callers. Report by Aleksei on pgsql-bugs on Dec 22 2009. Backpatch to 8.1, like the previous patch that broke this.	16 years ago
Tom Lane	a5495cd841	Add a hook to let loadable modules get control at ProcessUtility execution, and use it to extend contrib/pg_stat_statements to track utility commands. Itagaki Takahiro, reviewed by Euler Taveira de Oliveira.	16 years ago
Robert Haas	cddca5ec13	Add an EXPLAIN (BUFFERS) option to show buffer-usage statistics. This patch also removes buffer-usage statistics from the track_counts output, since this (or the global server statistics) is deemed to be a better interface to this information. Itagaki Takahiro, reviewed by Euler Taveira de Oliveira.	16 years ago

Tom Lane	e4b9e65393	Fix pg_stat_statements for EXEC_BACKEND case. We should not try to load old statistics when re-attaching to existing shared memory. Per bug #4941. Itagaki Takahiro	16 years ago
