to_char doesn't have adequate logic for locale-specific monetary formatting.
You can get it to emit a locale-specific currency symbol, but it has no
clue whether that should go before or after the value. It knows nothing
of other locale-specific details, such as possibly using parens in place
of a minus sign. Also, the POSIX API allows monetary decimal point and
thousands separators to be different from the numeric ones that to_char
knows about. (I have no idea which locales use that, but I doubt they'd
have put in that complication without need.)
