No, I don't address that point in this book.

It gives you plenty SQL techniques to avoid ever having to LOOP in a PL/pgSQL function, and show how to use PL/SQL rather than PL/pgSQL each time it is possible, though.

Sweet. I'll give your book a read then. Gaining a more solid SQL foundation to avoid LOOP in the first place is what I need.
