It may be poor design to use OID, but have you ever tried to use a SERIAL field instead?
That alternative is a really poor choice, many headaches when you try to move data to other tables or recover a backup. There is a temptation to use the value in the SERIAL field but it is totaly useless in most cases. Duplicate values, etc.
