Yes indeed, looks very promising. I see there are also test frameworks available at http://en.dklab.ru/lib/dklab_pgunit/ and http://www.epictest.org/ . This will take me a while to digest, but hopefully I'll be able to scrap, or greatly simplify, my elaborate homemade test functions too. It's always a joy to be able to replace my own code with somebody else's. ~ Ken -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
