Revision 9a743ffdd6b2fe7a24089fc97d8efc98884e337d authored by Tom Lane on 15 October 2011, 00:24:57 UTC, committed by Tom Lane on 15 October 2011, 00:24:57 UTC 
Fix bugs in information_schema.referential_constraints view.
 
This view was being insufficiently careful about matching the FK constraint
to the depended-on primary or unique key constraint.  That could result in
failure to show an FK constraint at all, or showing it multiple times, or
claiming that it depended on a different constraint than the one it really
does.  Fix by joining via pg_depend to ensure that we find only the correct
dependency.

Back-patch, but don't bump catversion because we can't force initdb in back
branches.  The next minor-version release notes should explain that if you
need to fix this in an existing installation, you can drop the
information_schema schema then re-create it by sourcing
$SHAREDIR/information_schema.sql in each database (as a superuser of
course).
