To use 'LATIN1 encoding you need compatible locale. You can specify it
at initdb stage as for example:

>initdb --locale en_CA.ISO-8859-1 -E LATIN1 -d D:/data # -E LATIN1 is redundant in such case

Futhermore since PostgreSQL 8.4 you can specify LC_COLLATE and
LC_CTYPE with CREATE DATABASE command (and createdb wrapper), so these
settings are not "frozen" with database cluster.
