pg_dumpall

PostgreSQL 7.3.1 on i686-pc-linux-gnu, compiled by GCC 2.96

I issue the following command:
CREATE DATABASE "CISX" WITH OWNER = postgres TEMPLATE = template1 ENCODING = 'SQL_ASCII';

When I do a backup from the database using pg_dumpall (with no command line options) it creates the following:
CREATE DATABASE "CISX" WITH OWNER = postgres TEMPLATE = template0 ENCODING = 'SQL_ASCII';

I don't know whether this is a bug or not as I can't find any hard documentation to say otherwise?
There seems to be some kind of indication that this is the case for pg_dump but it's not clear.
Can someone clarify this, am I missing something obvious here?
If this is the case will there be a possible fix for this in the future?
