template1, can there be a template2/3/4?

as i understand the usage of template1, it holds the system catalogs,
users, etc, etc.

it is accessed as a quasi-shadow database supporting the actual production
data databases.

would it be possible for me to create a template2 and have some arbitrary
database use it instead of template1?

the reason i ask this is that it would be useful to have something to the
effect of:

database access startup for "sample" database.

if exists sample_cat database, use it instead of template1
otherwise use template1

this way "sample" could have its own set of users, permissions, etc, etc.

it would be a method for getting around the fact that a user in template1
has access to all of the other databases, modulo per-database permissions
via GRANT/REVOKE

does this make any sense?
