> I slightly prefer 3b) because it's smaller, what's your opinions? This is just another variation on the theme of kluging the catcache to do something it shouldn't. You're still building a catcache on a non-unique index, and that is going to lead to trouble. (I'm a bit surprised that there is no Assert in catcache.c checking that the index nominated to support a catcache is unique ...) regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
