Ideas on how to uniquely name the first and second set of "perc,

You can use alias-names for the 2 queries, like:
test=*# select foobar.a as x, foobar.b as y, bar.* from (select * from foo()) foobar, (select * from foo()) bar ;
You don't really need the sub-selects: you can put aliases on functions
in FROM.
select * from foo(...) as f1(a,b), foo(...) as f2(x,y);

Thanks Tom, Andreas, and Osvaldo...
I've found I really need these on the Select part rather than the From.
select otherstuff.*, foo(...) as f1(a,b), foo(...) as f2(x,y) from
otherstuff;
...won't work. It says:
subquery must return only one column
Funny thing is
select (foo(...)).*, (foo(...)).*;
...works fine, just has duplicate column names, so they are hard to get at.
I modeled this after examples here
http://www.postgresonline.com/journal/index.php?/archives/129-Use-of-OUT-and-INOUT-Parameters.html
I really only want a single record back from my function, but the
multi-record return looked easier. I need some kind of control of how
the columns are named per call.
Maybe this isn't possible... not alot of docs in this area.
Thanks,
Scott
