Ah! I found out now! If you set the local in your /etc/postgresql/postmaster.init to an appropriate one, it nearly gets it right. If I set: LANG=en_GB I get european conventions, but if I leave it unset (the default) I get US conventions. Of course, if I set it for 'en_NZ' I get US conventions. Perhaps en_NZ is not valid?
