I also thought about this but I guess I have to INSERT the dependency in pg_depend too. assuming the receiver function is in the same namespace as the type I’d do something like this: UPDATE pg_catalog.pg_type t SET typreceive = ‘my_recv', typsend = ‘my_send' WHERE t.typname = ‘my_type’; INSERT INTO pg_catalog.pg_depend (classid, objid, objsubid, refclassid, refobjid, refobjsubid, deptype) SELECT c.oid AS classid, p.oid as objid, 0 AS objsubid, refc.oid AS refclassid, t.oid AS refobjid, 0 AS refobjsubid, 'n' AS deptype FROM pg_catalog.pg_class c, pg_catalog.pg_proc p, pg_catalog.pg_class refc, pg_catalog.pg_type t WHERE c.relname='pg_proc' AND p.proname IN(‘my_recv', ‘my_send') AND refc.relname = 'pg_type' AND t.typname =‘my_type' AND p.pronamespace = t.typnamespace AND c.relnamespace = refc.relnamespace AND c.relnamespace = (SELECT oid FROM pg_catalog.pg_namespace WHERE nspname = 'pg_catalog’); Are there any other pg_catalog tables that might need informations? thanks Manuel -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
