I suspect your problem is that you're trying to load the data with DateStyle set to some setting other than what this constraint is hard-wired to assume. Personally I'd suggest replacing the LIKEs with something using EXTRACTs, or some other way that doesn't depend on the textual formatting of dates. 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
