Re: [GENERAL] 'Infinity' in date columns?

You seem to be carefully reading around the middle column in Table 8-13, which specifically shows that infinity doesn't work for type date. Oh, duh, right you are... Now, if you were to update to Postgres 8.4, it *would* work. I'll see if I can get my host to do that. ~ Thanks ~ Ken -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
