I assume from this that you are trying to implement something like Oracle's Virtual Private Database. If you need access controls at the row or column level, and do not want to implement this whole thing yourself, please take a look at Veil (http://veil.projects.postgresql.org/) which can already accomplish the same sort of thing, though in a different way. If Veil is insufficient for your needs in some way, I'd be interested to hear about it. __ Marc
