It isn't. CREATE DATABASE merely copies the source database as it stands
at that instant, there's no persistent relationship.
If you like you can create the target database by hand, using the new
template database, before restoring into it; but what is likely to
happen is that you get a lot of 'duplicate object' errors from objects
that were in the dump due to having been copied from the previous
incarnation of the template. Sometimes this is okay, but you'll want to
scan through the messages and make sure nothing undesirable happened.
