I haven't followed this thread too closely, but if you are trying to use
a SQL function for a trigger, it won't work. From the docs:
(http://www.us.postgresql.org/users-lounge/docs/7.3/postgres/triggers.html)

"Trigger functions can be written in C and most procedural languages,
but not in SQL"

Try re-writing your function in PL/pgSQL. BTW, I think I saw from your
other post that you don't have PL/pgSQL installed in the database you
are using. See the createlang program or CREATE LANGUAGE statement:
http://www.us.postgresql.org/users-lounge/docs/7.3/postgres/app-createlang.html
http://www.us.postgresql.org/users-lounge/docs/7.3/postgres/sql-createlanguage.html

HTH,
