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	8a859691d5	Properly initialize SortSupport for ORDER BY rechecks in nodeIndexscan.c. ... 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.

Heikki Linnakangas	e09b48316c	Add index-only scan support to btree_gist. ... inet, cidr, and timetz indexes still cannot support index-only scans, because they don't store the original unmodified value in the index, but a derived approximate value.	11 years ago
Tom Lane	8436489c81	Add KNNGIST support to contrib/btree_gist. ... This extends GiST's support for nearest-neighbor searches to many of the standard data types. Teodor Sigaev	15 years ago
Teodor Sigaev	42d069886f	New version. Add support for int2, int8, float4, float8, timestamp with/without time zone, time with/without time zone, date, interval, oid, money and macaddr, char, varchar/text, bytea, numeric, bit, varbit, inet/cidr types for GiST	22 years ago
