David J,
If the whole purpose of a template is to be a basis for an additional user database than what admi tasks are defined in
template1 and template 0 does matter, because if template 0 would never be used as a db in it's own right, it's
descendantswould be.
For instance:
Template 0 does not contain the language encodings and collation settings specific to the os on which postgres is
runningtemplate 1 does, so if you want to create a db with language settings other than what is in template 1 you would
usetemplate 0, and if template 0 does not contain "admin tasks" than it would have to be administered manually....
Sincerely,
Kasia

If you are referring to instructions to perform cluster-wide maintenance (i.e., create data, create role) while
connectedto the "template1" database that it mostly a matter of convenience. template0 should not be used (if it even
canbe connected to) for administrative tasks because template1 has to exist and is better suited from a logical
standpointto fulfill that role.
The postgres default database is also a viable candidate but often people will drop it if they feel it is not useful.
