Dear Gurus,
Please show me to the archives, if you feel like. I have an ugly function
that can't be defined as language SQL, because it gets parsed at
define-time, not run-time. Any ideas, other than making it plpgsql?
Even better, is there a more elegant way to turn off/on triggers on a (set
of) table(s)?
The function and what psql says is at the end of this message.
G.
