I believe the initial email requested individual logs, and presumably
the ability to grant superuser access without risking a user crossing
into another clients space.
The only way to accomplish this is to run 2 copies. Last time I looked,
you couldn't get the database name in the log files to allow for
mechanical filtering, and a number of abilities are still only available
to superusers -- not through grants or specific permissions.
