Guys, this is pretty straightforward. The permissions on the view
determine who can access it. The permissions of the view owner
determine what the view can access. The way to think about this may
be that a view acts a bit like a setuid program under UNIX: a regular
user can gain superuser privileges; a superuser can give them up.
This may or may not make sense to you and it may or may not be what
you want, but it's NOT A BUG. It's done that way on purpose, it's
well-documented, and it's been that way for a long time. If you want
some explanation of WHY is that way and what it might be useful for,
start by reading the documentation and then if you have questions, ask
on the appropriate mailing list, maybe pgsql-general or pgsql-novice.
