I actually just did that for a database.

The caveats are noted here:

http://www.postgresql.org/docs/9.3/interactive/sql-createdatabase.html

"Although it is possible to copy a database other than template1 by
specifying its name as the template, this is not (yet) intended as a
general-purpose "COPY DATABASE" facility. The principal limitation is
that no other sessions can be connected to the template database while
it is being copied. CREATE DATABASE will fail if any other connection
exists when it starts; otherwise, new connections to the template
database are locked out until CREATE DATABASE completes. See Section
21.3 for more information
