Does postgres have a concept of a 'root' user? Then the password should
only be prompted when one isn't root; ie. adopt Unix semantics.

Can't really do that in psql's \c, since it's establishing a whole new
connection; there is no possibility for superuserness on the old
connection to provide any relaxation of the check.

However, see SET SESSION AUTHORIZATION, which does what you're thinking
of within the context of a single connection.
