The code will try to remove the existing schema contents (as indicated by pg_depend), and evidently there is something inconsistent in that. What rows do you have in pg_depend that have either objid or refobjid equal to 463558 or 463559? Also, get the OID of the pg_temp_4 schema from pg_namespace, and see what rows in pg_depend have refobjid equal to that. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
