How are variables in pg/psql functions passed? I'm sure this is documented somewhere. I looked but no joy. A link would be great! TIA

I doubt its documented anywhere since the concept of "by reference" is not part of the language. The concept is also not part of SQL.

If you want a better explanation you should provide some code for us to comment upon.
