You can return an array value from plpgsql, no problem. The problem is
that plpgsql is pretty weak on functionality for constructing an array
value on the fly. I think the only way that would work is to build up
a textual representation of an array literal ('{foo,bar,baz}') and then
rely on runtime type conversion to do the right thing when you try to
RETURN the text string from a function declared as returning int[] or
whatever.
You might have better luck doing this in pltcl or plperl, either of
which have string-mashing facilities far superior to plpgsql.
