Some people think that cross-database user names are a feature, not
a bug. I cannot see any way to change that without creating huge
backward-compatibility headaches --- and it's not at all clear to
me that it's a step forward, anyway.
I think that it might be worth adding a CONNECT privilege at the
database level; that together with Bruce's recent revisions to
pg_hba.conf ought to be a pretty good improvement.
