I think this is a very good idea. I've come up against this need once or
twice before.. And the fact that stuff in template1 gets propagated out
to all newly created databases can be a major pain when this happens.

A shared database for this stuff would be great - then each tool could
just create a schema for it's own stuff.

How does pgAdmin deal with this today?
