I wouldn't trust OIDs, because they are 32bits for once. Secondly, Watch for index size. That's the main reason why (big)int as a key reference is a win over other types - at least in my general practice.
And third advice, try different approaches, and queries - to figureout what would suit the solution. Anyone who says, that this is always win, and something else is not - is a lier. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
