Re: How to return a record and sets of record in plpython

As far as I understand, though I hope someone will post that I'm wrong,
plpython cannot return recordsets.
In general, I use plpgsql when I want recordets and plpython when I want
functionality.
I have also called plpython functions from a plpgsql function when I wanted
a single value result.
