Hi, Postgresql 8.2.13 on Windows (it's correct, "Leden" is the Czech translation of "January"): postgres=# SET lc_messages=en;select to_char('2006/01/01'::timestamp, 'TMMonth'); SET to_char --------- January postgres=# SET lc_messages=cs;select to_char('2006/01/01'::timestamp, 'TMMonth'); SET to_char --------- Leden Postgresql 8.3.7 on Windows (wrong): postgres=# SET lc_messages=en;select to_char('2006/01/01'::timestamp, 'TMMonth'); SET to_char --------- January postgres=# SET lc_messages=cs;select to_char('2006/01/01'::timestamp, 'TMMonth'); SET to_char --------- January Do you have any idea what happens in 8.3.7?
