Peter Eisentraut	630f9a43ce	Change gist stratnum function to use CompareType This changes commit `7406ab623f` in that the gist strategy number mapping support function is changed to use the CompareType enum as input, instead of the "well-known" RT*StrategyNumber strategy numbers. This is a bit cleaner, since you are not dealing with two sets of strategy numbers. Also, this will enable us to subsume this system into a more general system of using CompareType to define operator semantics across index methods.

Peter Eisentraut	7406ab623f	Add stratnum GiST support function This is support function 12 for the GiST AM and translates "well-known" RT*StrategyNumber values into whatever strategy number is used by the opclass (since no particular numbers are actually required). We will use this to support temporal PRIMARY KEY/UNIQUE/FOREIGN KEY/FOR PORTION OF functionality. This commit adds two implementations, one for internal GiST opclasses (just an identity function) and another for btree_gist opclasses. It updates btree_gist from 1.7 to 1.8, adding the support function for all its opclasses. (previously committed as `6db4598fcb`, reverted by 8aee330af55; this is essentially unchanged from those) Author: Paul A.

Peter Eisentraut	8aee330af5	Revert temporal primary keys and foreign keys This feature set did not handle empty ranges correctly, and it's now too late for PostgreSQL 17 to fix it. The following commits are reverted: `6db4598fcb` Add stratnum GiST support function `46a0cd4cef` Add temporal PRIMARY KEY and UNIQUE constraints `86232a49a4` Fix comment on gist_stratnum_btree `030e10ff1a` Rename pg_constraint.conwithoutoverlaps to conperiod `a88c800deb` Use daterange and YMD in without_overlaps tests instead of tsrange. `5577a71fb0` Use half-open interval notation in without_overlaps tests `34768ee361` Add temporal FOREIGN KEY contraints `482e108cd3` Add test for REPLICA IDENTITY with a temporal key `c3db1f30cb` doc: clarify PERIOD and WITHOUT OVERLAPS in CREATE TABLE `144c2ce0cc` Fix ON CONFLICT DO NOTHING/UPDATE for temporal indexes Discussion: https://www.postgresql.org/message-id/d0b64a7a-dfe4-4b84-a906-c7dedfa40a3e@eisentraut.org	2 years ago
