The real point I was trying to convey (in my previous email) is that
these declarations should be part of the trigger *function* not the
function-to-table relationship. CREATE TRIGGER shouldn't be in the
business of declaring new local variables for the trigger function.
Whether we define new syntax for that or re-use the argument list is
secondary.

But the inconsistency is deliberate, I find the current trigger API
horrible. Magic variables... Text-only TG_ARGV for arguments...
RETURNS trigger... No way to invoke trigger functions directly for
testing.

By not imitating past mistakes, maybe we can eventually arrive at a
language that makes sense.
