You can't realistically attach such things to a domain; try making a separate type, perhaps with an implicit cast to text to allow use of text operators for other purposes. Elein was going to look into tweaking the coercion rules so that functions on domains had a non-negligible chance of being useful, but we've not heard much about that project lately. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
