Wow, nevermind. What I must not understand is my own code. Yikes, what
a bonehead.
From both User A and User B, this query returns rows:
select * from pg_trigger where tgname = '<name>'
but User A gets 2 rows (because I have the same trigger name on two
different tables) while User B only sees one of them. Is it permissions
on pg_trigger or on the original table (or some other thing) that is
preventing B from seeing that row?
