This will work a lot better as of 8.2; we've added a CONNECT privilege
for databases that can be manipulated with ordinary GRANT/REVOKE commands.
Unfortunately that's not in any released version :-(

For the moment, the easiest way to handle it is via groups. The trick
is to create a group associated with each database (and named the same
as the database), then use the "samegroup" option in pg_hba.conf to show
that people can log into databases if they are members of the
corresponding group. Then granting and revoking group membership gets
the job done without any changes in pg_hba.conf.
