From 8aee330af55d8a759b2b73f5a771d9d34a7b887f Mon Sep 17 00:00:00 2001 From: Peter Eisentraut Date: Thu, 16 May 2024 08:15:35 +0200 Subject: 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: 6db4598fcb8 Add stratnum GiST support function 46a0cd4cefb Add temporal PRIMARY KEY and UNIQUE constraints 86232a49a43 Fix comment on gist_stratnum_btree 030e10ff1a3 Rename pg_constraint.conwithoutoverlaps to conperiod a88c800deb6 Use daterange and YMD in without_overlaps tests instead of tsrange. 5577a71fb0c Use half-open interval notation in without_overlaps tests 34768ee3616 Add temporal FOREIGN KEY contraints 482e108cd38 Add test for REPLICA IDENTITY with a temporal key c3db1f30cba doc: clarify PERIOD and WITHOUT OVERLAPS in CREATE TABLE 144c2ce0cc7 Fix ON CONFLICT DO NOTHING/UPDATE for temporal indexes Discussion: https://www.postgresql.org/message-id/d0b64a7a-dfe4-4b84-a906-c7dedfa40a3e@eisentraut.org --- src/backend/access/gist/gistutil.c | 43 -------------------------------------- 1 file changed, 43 deletions(-) (limited to 'src/backend/access/gist/gistutil.c') diff --git a/src/backend/access/gist/gistutil.c b/src/backend/access/gist/gistutil.c index d2d0b36d4ea..78e98d68b15 100644 --- a/src/backend/access/gist/gistutil.c +++ b/src/backend/access/gist/gistutil.c @@ -21,7 +21,6 @@ #include "common/pg_prng.h" #include "storage/indexfsm.h" #include "utils/float.h" -#include "utils/fmgrprotos.h" #include "utils/lsyscache.h" #include "utils/rel.h" #include "utils/snapmgr.h" @@ -1056,45 +1055,3 @@ gistGetFakeLSN(Relation rel) return GetFakeLSNForUnloggedRel(); } } - -/* - * Returns the same number that was received. - * - * This is for GiST opclasses that use the RT*StrategyNumber constants. - */ -Datum -gist_stratnum_identity(PG_FUNCTION_ARGS) -{ - StrategyNumber strat = PG_GETARG_UINT16(0); - - PG_RETURN_UINT16(strat); -} - -/* - * Returns the opclass's private stratnum used for the given strategy. - * - * Calls the opclass's GIST_STRATNUM_PROC support function, if any, - * and returns the result. - * Returns InvalidStrategy if the function is not defined. - */ -StrategyNumber -GistTranslateStratnum(Oid opclass, StrategyNumber strat) -{ - Oid opfamily; - Oid opcintype; - Oid funcid; - Datum result; - - /* Look up the opclass family and input datatype. */ - if (!get_opclass_opfamily_and_input_type(opclass, &opfamily, &opcintype)) - return InvalidStrategy; - - /* Check whether the function is provided. */ - funcid = get_opfamily_proc(opfamily, opcintype, opcintype, GIST_STRATNUM_PROC); - if (!OidIsValid(funcid)) - return InvalidStrategy; - - /* Ask the translation function */ - result = OidFunctionCall1Coll(funcid, InvalidOid, UInt16GetDatum(strat)); - return DatumGetUInt16(result); -} -- cgit v1.2.3
