2021-04-07	Revert "Add sortsupport for gist_btree opclasses, for faster index builds."	Heikki Linnakangas
	This reverts commit 9f984ba6d23dc6eecebf479ab1d3f2e550a4e9be. 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.
2021-04-07	Add sortsupport for gist_btree opclasses, for faster index builds.	Heikki Linnakangas
	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. Author: Andrey Borodin Discussion: https://www.postgresql.org/message-id/[email protected]
2016-06-05	Properly initialize SortSupport for ORDER BY rechecks in nodeIndexscan.c.	Tom Lane
	Fix still another bug in commit 35fcb1b3d: it failed to fully initialize the SortSupport states it introduced to allow the executor to re-check ORDER BY expressions containing distance operators. That led to a null pointer dereference if the sortsupport code tried to use ssup_cxt. The problem only manifests in narrow cases, explaining the lack of previous field reports. It requires a GiST-indexable distance operator that lacks SortSupport and is on a pass-by-ref data type, which among core+contrib seems to be only btree_gist's interval opclass; and it requires the scan to be done as an IndexScan not an IndexOnlyScan, which explains how btree_gist's regression test didn't catch it. Per bug #14134 from Jihyun Yu. Peter Geoghegan Report: <[email protected]>
