Hi,
I am running performance simulation against a DB. I want to randomly pull different records from a large table. However the table has no columns that hold sequential integer values (1..MAX), i.e. the columns all have "holes" (due to earlier filtering). Also PG does not have a concept of an auto-increment pseudo-column like Oracle's "rownum". Any suggestions?
Thanks,
