I understand, now. You're trying to replicate the functionality
provided in programming languages using By Reference arguments.

I could suggest a number of workarounds. However, I think rather that
you should give serious consideration to *not* doing this in PL/pgSQL
but doing it in a full-featured procedural (and/or Object Oriented)
language instead. Java, Python, Perl and even 4GL would provide you
with more robust functionality.

For example, what you want is easily done in Java just by passing the
input parameters as By Reference.

Opinions on Middleware languages, anyone?
