Turns out that's bogus - ALTER TABLE has two levels of NOT EXISTS.

DROP TRIGGER [ IF EXISTS ] name ON table_name [ IF EXISTS ] [ CASCADE | RESTRICT ]

I am unconvinced that that's the case when using the existing IF EXISTS
for DROP TRIGGER, but my complaints would be completely addressed by
making it a separate flag.
