Heikki Linnakangas	d92b1cdbab	Revert "Add sortsupport for gist_btree opclasses, for faster index builds." ... This reverts commit 9f984ba6d2. It was making the buildfarm unhappy, apparently setting client_min_messages in a regression test produces different output if log_statement='all'. Another issue is that I now suspect the bit sortsupport function was in fact not correct to call byteacmp(). Revert to investigate both of those issues.	5 years ago
Heikki Linnakangas	9f984ba6d2	Add sortsupport for gist_btree opclasses, for faster index builds. ... Commit 16fa9b2b30 introduced a faster way to build GiST indexes, by sorting all the data. This commit adds the sortsupport functions needed to make use of that feature for btree_gist.

Tom Lane	17d6a8fb76	Improve stability of recently-added regression test case. ... Commit b5febc1d1 added a contrib/btree_gist test case that has been observed to fail in the buildfarm as a result of background auto-analyze updating stats and changing the selected plan. Forestall that by forcibly analyzing in foreground, instead. The new plan choice is just as good for our purposes, since we really only care that an index-only plan does not get selected. Back-patch to 9.5, like the previous patch. Discussion: https://postgr.es/m/14643.1539629304@sss.pgh.pa.us	7 years ago
Tom Lane	b5febc1d12	Fix IOS planning when only some index columns can return an attribute. ... Since 9.5, it's possible that some but not all columns of an index support returning the indexed value for index-only scans. If the same indexed column appears in index columns that behave both ways, check_index_only() supposed that it'd be OK to do an index-only scan testing that column; but that fails if we have to recheck the indexed condition on one of the columns that doesn't support this. In principle we could make this work by remapping the recheck expressions to pull the value from a column that does support returning the indexed value. But such cases are so weird and rare that, at least for now, it doesn't seem worth the trouble. Instead, just teach check_index_only that a value is returnable only if all the index columns containing it are returnable, rather than any of them. Per report from David Pereiro Lagares. Back-patch to 9.5 where the possibility of this situation appeared. Kyotaro Horiguchi Discussion: https://postgr.es/m/1516210494.1798.16.camel@nlpgo.com	8 years ago
