I have in fact tried that very thing. pgAdminII has a Log View that is
supposed to show all the back-end SQL that it executes in order to show you
what it does. However, all it really does is retrieve the pg_triggers.tgargs
field, which is 6 fields separated by \0's, then it must parse it internally.

I'm looking for a way to parse 'one\000two\000three\000'::bytea into
foo1 | foo2 | foo3
------+------+-------one  | two  | three

using only (Postgre)SQL, no external C functions or the like. Ideas? I'm
looking into PL/pgSQL as a solution, but haven't gotten very far yet.
