I was referring to threads like:
         http://archives.postgresql.org/pgsql-sql/2004-10/msg00124.php
and threads on 9.Feb.2006 and 11.Mar.2006, which are on my system, but not 
on the above archive site.  The various threads point to this page:
         http://www.postgresql.org/docs/8.1/interactive/xaggr.html
Specifically the "array_accum" function on that page.
