En,I have that damm problem sloved.
Are you using a Non-English Version of Windows? for example,JPN,CHS?
If you install your Psql in an Asian-language windows,be sure that "locale" settings should be setted manualy to a supported language,I choosed "C" for it is the first item in the combo.

this is the errmsg when you're using default local settings:
