To my mind the real advantage of doing it in a trigger is that
CREATE USER WITH PASSWORD and ALTER USER SET PASSWORD can accept
*either* cleartext or already-hashed password data.  That seems
nicer than forcing the user to deal with two syntaxes, upgrade
scripts, etc.

How far down the pipe?  It'd be nice if we could fix pg_dumpall to
dump CREATE USER commands a version before we actually need it ;-).
I'd like to change the script for 7.1 (or maybe even 7.0.1) but keep
backwards compatibility for the old-style dump scripts until 7.2.
(At the moment I'm kind of kicking myself for not having fixed the
problem when I saw it, but there was no talk of pg_shadow changes
in the air at the time.)
