pgsql: Use thread-safe strftime_l() instead of strftime().

From

Use thread-safe strftime_l() instead of strftime().

This removes some setlocale() calls and a lot of commentary about how
dangerous that is.  strftime_l() is from POSIX 2008, and on Windows we
use _wcsftime_l().

While here, adjust error message for strftime_l() failure: it does not
in practice set errno (even though POSIX says it could), so no %m.
