About the groups: I just want to write a function that will return the users
names belonged by a given group. I understand I can load the arrays in
memory, then sequentially compare the members from pg_shadow, but doing it
goes against the database priciple after all.
About the procs: the Borland's dbExpress specification demands a
input/output list of parameters for stored procedures, and I'm going to use
functions as stored procedures. But I need to make a types list to be able
list what are those params.

This design itself bothers me.
We have no other option left  ? Like arrays being referenced in relations ?
That's far from perfect, but at least would solve those issues and others
which might appear in other catalogs...
