* Clean up code associated with updating pg_class statistics columnsTom Lane2006-05-1017-404/+519
| | | | | | | | | | | (relpages/reltuples). To do this, create formal support in heapam.c for "overwrite" tuple updates (including xlog replay capability) and use that instead of the ad-hoc overwrites we'd been using in VACUUM and CREATE INDEX. Take the responsibility for updating stats during CREATE INDEX out of the individual index AMs, and do it where it belongs, in catalog/index.c. Aside from being more modular, this avoids having to update the same tuple twice in some paths through CREATE INDEX. It's probably not measurably faster, but for sure it's a lot cleaner than before.

* Rewrite btree vacuuming to fold the former bulkdelete and cleanup operationsTom Lane2006-05-0810-243/+682
| | | | | | | | | | | | | into a single mostly-physical-order scan of the index. This requires some ticklish interlocking considerations, but should create no material performance impact on normal index operations (at least given the already-committed changes to make scans work a page at a time). VACUUM itself should get significantly faster in any index that's degenerated to a very nonlinear page order. Also, we save one pass over the index entirely, except in the case where there were no deletions to do and so only one pass happened anyway. Original patch by Heikki Linnakangas, rework by Tom Lane.
* Rewrite btree index scans to work a page at a time in all cases (bothTom Lane2006-05-079-629/+624
| | | | | | | | | | | | | | | | btgettuple and btgetmulti). This eliminates the problem of "re-finding" the exact stopping point, since the stopping point is effectively always a page boundary, and index items are never moved across pre-existing page boundaries. A small penalty is that the keys_are_unique optimization is effectively disabled (and, therefore, is removed in this patch), causing us to apply _bt_checkkeys() to at least one more tuple than necessary when looking up a unique key. However, the advantages for non-unique cases seem great enough to accept this tradeoff. Aside from simplifying and (sometimes) speeding up the indexscan code, this will allow us to reimplement btbulkdelete as a largely sequential scan instead of index-order traversal, thereby significantly reducing the cost of VACUUM. Those changes will come in a separate patch. Original patch by Heikki Linnakangas, rework by Tom Lane.

* Simplify relcache startup sequence. With the new design of InitPostgresTom Lane2006-05-043-55/+49
| | | | | | | it's not necessary to have three separate calls anymore. This patch also fixes things so we don't try to read pg_internal.init until after we've obtained lock on the target database; which was fairly harmless, but it's certainly cleaner this way.
* Rethink the locking mechanisms used for CREATE/DROP/RENAME DATABASE.Tom Lane2006-05-049-405/+451
| | | | | | | | | | | | | The former approach used ExclusiveLock on pg_database, which being a cluster-wide lock meant only one of these operations could proceed at a time; worse, it also blocked all incoming connections in ReverifyMyDatabase. Now that we have LockSharedObject(), we can use locks of different types applied to databases considered as objects. This allows much more flexible management of the interlocking: two CREATE DATABASEs need not block each other, and need not block connections except to the template database being used. Similarly DROP DATABASE doesn't block unrelated operations. The locking used in flatfiles.c is also much narrower in scope than before. Per recent proposal.
* Create a syscache for pg_database-indexed-by-oid, and make use of itTom Lane2006-05-038-205/+116
| | | | | | | | | | in various places that were previously doing ad hoc pg_database searches. This may speed up database-related privilege checks a little bit, but the main motivation is to eliminate the performance reason for having ReverifyMyDatabase do such a lot of stuff (viz, avoiding repeat scans of pg_database during backend startup). The locking reason for having that routine is about to go away, and it'd be good to have the option to break it up.

| | | | | | | | | | | | initPlan sets a parameter for another. This could not (I think) happen before 8.1, but it's possible now because the initPlans generated by MIN/MAX optimization might themselves use initPlans. We attach those initPlans as siblings of the MIN/MAX ones, not children, to avoid duplicate computation when multiple MIN/MAX aggregates are present; so this leads to the case of an initPlan needing the result of a sibling initPlan, which is not possible with ordinary query nesting. Hadn't been noticed because in most contexts having too much stuff listed in extParam is fairly harmless. Fixes "plan should not reference subplan's variable" bug reported by Catalin Pitis.

* Avoid assuming that statistics for a parent relation reflect the properties ofTom Lane2006-05-022-6/+21
| | | | | | | | | | | | | the union of its child relations as well. This might have been a good idea when it was originally coded, but it's a fatally bad idea when inheritance is being used for partitioning. It's better to have no stats at all than completely misleading stats. Per report from Mark Liberman. The bug arguably exists all the way back, but I've only patched HEAD and 8.1 because we weren't particularly trying to support partitioning before 8.1. Eventually we ought to look at deriving union statistics instead of just punting, but for now the drop kick looks good.

This is faster than the old method when there's an exact match, and it does not seem materially slower when there's not. And it definitely makes some of the callers cleaner, because they didn't really want to know about a list of candidates anyway. Per discussion with Atsushi Ogawa.
