Subject: [PATCH] Fix incorrect permissions check in
information_schema.key_column_usage view: it was checking a pg_constraint OID
instead of pg_class OID, resulting in "relation with OID nnnnn does not
exist" failures for anyone who wasn't owner of the table being examined. Per
bug #2848 from Laurence Rowe.
Note: for existing 8.2 installations a simple version update won't fix this;
the easiest fix is to CREATE OR REPLACE this view with the corrected
definition.
