Perhaps one of the requirements of a new auth method should be to allow
middlemen such as connection poolers.  It's been over two years since I
had a look, but IIRC pgbouncer had the very ugly requirement of its own
copy of user/passwords in a file, and of course you had to update it
separately if you changed the password in the server.  We need to make
it possible for it not to require any such thing.
