pgsql: setlocale() on Windows doesn't work correctly if the locale name

setlocale() on Windows doesn't work correctly if the locale name contains
apostrophes or dots. There isn't much hope of Microsoft fixing it any time
soon, it's been like that for ages, so we better work around it. So, map a
few common Windows locale names known to cause problems to aliases that work.
