From f5bcd398addcbeb785f0513cf28cba5d1ecd2c8a Mon Sep 17 00:00:00 2001 From: Alvaro Herrera Date: Fri, 20 Jul 2012 12:33:34 -0400 Subject: [PATCH] connoinherit may be true only for CHECK constraints MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The code was setting it true for other constraints, which is bogus. Doing so caused bogus catalog entries for such constraints, and in particular caused an error to be raised when trying to drop a constraint of types other than CHECK from a table that has children, such as reported in bug #6712. In 9.2, additionally ignore connoinherit=true for other constraint types, to avoid having to force initdb; existing databases might already contain bogus catalog entries. Includes a catversion bump (in HEAD only). Bug report from Miroslav Å ulc Analysis from Amit Kapila and Noah Misch; Amit also contributed the patch. --- src/backend/catalog/index.c | 2 +- src/backend/commands/tablecmds.c | 2 +- src/backend/commands/trigger.c | 2 +- src/include/catalog/catversion.h | 2 +- src/test/regress/expected/inherit.out | 117 ++++++++++++++++++++++++++ src/test/regress/sql/inherit.sql | 36 ++++++++ 6 files changed, 157 insertions(+), 4 deletions(-) diff --git a/src/backend/catalog/index.c b/src/backend/catalog/index.c index 0c51923be8..1546d480e3 100644 --- a/src/backend/catalog/index.c +++ b/src/backend/catalog/index.c @@ -1154,7 +1154,7 @@ index_constraint_create(Relation heapRelation, NULL, true, /* islocal */ 0, /* inhcount */ - false);
