Hi,

I think, it should be possible without changing template0/template1, 
simply by using template0 and -E parameter to (command line) createdb.

Examples:

createdb -T template0 -E latin1 foo
createdb -T template0 -E sql_ascii foo2
createdb -T template0 -E EUC_CN foo3
createdb -T template0 -E utf8 foo4


np ->psql -l |grep foo
 foo        | np                  | LATIN1    | C       | C     | 
 foo2       | np                  | SQL_ASCII | C       | C     | 
 foo3       | np                  | EUC_CN    | C       | C     | 
 foo4       | np                  | UTF8      | C       | C     | 



cheers
Norbert
