Got it. Thanks! I feel silly not to have tried that. Somehow I interpreted "cannot be cast automatically to type uuid[]" as meaning that it cannot be cast at all (and would therefore need a more involved expression to specify how to convert it), rather than that the cast merely needed to be explicit. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
