to_char() has long allowed the TM (translation mode) prefix to specify output of translated month or day names; but that prefix had no effect in input format strings. Now it does. to_date() and to_timestamp() will now recognize the same month or day names that to_char() would output for the same format code. Matching is case-insensitive (per the active collation's notion of what that means), just as it has always been for English month/day names without the TM prefix. (As per the discussion thread, there are lots of cases that this feature will not handle, such as alternate day names. But being able to accept what to_char() will output seems useful enough.) In passing, fix some shaky English and violations of message style guidelines in jsonpath errors for the .datetime() method, which depends on this code.
