Yeah, the syntax has to be "scalar operator ALL (array)". > Could anyone please recommend a way to implement check constraints here? The workaround that's been suggested in the past is to define a reversed pattern match operator, ie one that has the pattern on the left. There's no such thing in the core PG distribution, but the only hard part of making your own is figuring out what to name the operator ;-) 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
