Michael Paquier	736b84eede	Fix failure with lock mode used for custom relation options ... In-core relation options can use a custom lock mode since 47167b7, that has lowered the lock available for some autovacuum parameters. However it forgot to consider custom relation options. This causes failures with ALTER TABLE SET when changing a custom relation option, as its lock is not defined. The existing APIs to define a custom reloption does not allow to define a custom lock mode, so enforce its initialization to AccessExclusiveMode which should be safe enough in all cases. An upcoming patch will extend the existing APIs to allow a custom lock mode to be defined. The problem can be reproduced with bloom indexes, so add a test there.

Tom Lane	abaffa9075	Fix contrib/bloom to work for unlogged indexes. ... blbuildempty did not do even approximately the right thing: it tried to add a metapage to the relation's regular data fork, which already has one at that point. It should look like the ambuildempty methods for all the standard index types, ie, initialize a metapage image in some transient storage and then write it directly to the init fork. To support that, refactor BloomInitMetapage into two functions. In passing, fix BloomInitMetapage so it doesn't leave the rd_options field of the index's relcache entry pointing at transient storage. I'm not sure this had any visible consequence, since nothing much else is likely to look at a bloom index's rd_options, but it's certainly poor practice. Per bug #14155 from Zhou Digoal.

Tom Lane	cf223c3bf5	Improve contrib/bloom regression test using code coverage info. ... Originally, this test created a 100000-row test table, which made it run rather slowly compared to other contrib tests. Investigation with gcov showed that we got no further improvement in code coverage after the first 700 or so rows, making the large table 99% a waste of time. Cut it back to 2000 rows to fix the runtime problem and still leave some headroom for testing behaviors that may appear later. A closer look at the gcov results showed that the main coverage omissions in contrib/bloom occurred because the test never filled more than one entry in the notFullPage array; which is unsurprising because it exercised index cleanup only in the scenario of complete table deletion, allowing every page in the index to become deleted rather than not-full. Add testing that allows the not-full path to be exercised as well. Also, test the amvalidate function, because blvalidate.c had zero coverage without that, and besides it's a good idea to check for mistakes in the bloom opclass definitions.	10 years ago
Teodor Sigaev	9ee014fc89	Bloom index contrib module ... Module provides new access method. It is actually a simple Bloom filter implemented as pgsql's index. It could give some benefits on search with large number of columns. Module is a single way to test generic WAL interface committed earlier.
