It's worth noting that there's a conflict between the use of template1
as the default template for CREATE DATABASE, versus its use as the
default database-to-connect-to for scripts like createuser. You could
get a failure from CREATE DATABASE if someone happens to be transiently
connected to template1 while creating a user or whatever.
This is a historical accident that arises from the fact that template1
is the only certain-to-exist database name (other than template0 which
is a recent innovation). We're probably going to have to change some
of this stuff eventually...
