From b12ca1d56136db61d141ad160236b9f745bb354f Mon Sep 17 00:00:00 2001 From: Robert Haas Date: Tue, 22 Jun 2010 11:36:44 +0000 Subject: [PATCH] Deprecate the use of => as an operator name. In HEAD, emit a warning when an operator named => is defined. In both HEAD and the backbranches (except in 8.2, where contrib modules do not have documentation), document that hstore's text => text operator may be removed in a future release, and encourage the use of the hstore(text, text) function instead. This function only exists in HEAD (previously, it was called tconvert), so backpatch it back to 8.2, when hstore was added. Per discussion. --- contrib/hstore/hstore.sql.in | 6 ++++++ contrib/hstore/uninstall_hstore.sql | 1 + 2 files changed, 7 insertions(+) diff --git a/contrib/hstore/hstore.sql.in b/contrib/hstore/hstore.sql.in index 95cecf15d2..4e7c494694 100644 --- a/contrib/hstore/hstore.sql.in +++ b/contrib/hstore/hstore.sql.in @@ -118,6 +118,12 @@ RETURNS hstore AS 'MODULE_PATHNAME' LANGUAGE 'C' with (isstrict,iscachable); +-- For forward compatibility with PostgreSQL >= 9.0 +CREATE OR REPLACE FUNCTION hstore(text,text) +RETURNS hstore +AS 'MODULE_PATHNAME', 'tconvert' +LANGUAGE C IMMUTABLE; -- not STRICT + CREATE OPERATOR => ( LEFTARG = text, RIGHTARG = text, diff --git a/contrib/hstore/uninstall_hstore.sql b/contrib/hstore/uninstall_hstore.sql index bfa2e738dc..f0b9fa5e7b 100644 --- a/contrib/hstore/uninstall_hstore.sql +++ b/contrib/hstore/uninstall_hstore.sql @@ -21,6 +21,7 @@ DROP FUNCTION hs_concat(hstore,hstore); DROP FUNCTION hs_contains(hstore,hstore); DROP FUNCTION hs_contained(hstore,hstore); DROP FUNCTION tconvert(text,text); +DROP FUNCTION hstore(text,text); DROP FUNCTION akeys(hstore); DROP FUNCTION avals(hstore); DROP FUNCTION skeys(hstore);
