alias for OLD and NEW in triggers

Hi,

i want to make this patch usable
http://archives.postgresql.org/pgsql-patches/2004-12/msg00089.php

as i understand, it needs some refactor, at least plpgsql support,
pg_dump support and docs.

any comments are welcome...

also the autor states this:

why it's necessary and *critical* for implementing execution of standard SQL
commands in trigger action in future?
maybe i'm very wrong (very possible) but i see this just as make up...
i don't see how say 'old_row' is so different of saying 'OLD'
