pg_user "sealed"

Okay...

	I've modified initdb.sh so that ALL is revoked from pg_user, with
a view being created to look into it for usename and usesysid, which are
required by psql...

	This gets it so that psql works for \d

	I tried to do a rewrite rule on db_user such that password would
become '*********', but that does't appear to work?

	Reports of any problems associated with any of the pg_ system
tables, please let me know
