Karel,
> > OO in PostgreSQL means that you can create own operators, datetypes, functions... Last I checked, all of these things were part of the SQL spec. I believe our only "OO" functionality is inheritance ... which I have yet to find a use for. Of course, I agree with Fabian Pascal, who claims that every OODBMS "feature" has an answer in the SQL spec that is more consistent and better thought out. -- -Josh Berkus ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
