Re: Pasword expiration warning

+		if (password_expire_warning > 0 && vuntil < PG_INT64_MAX)
+		{
+			TimestampTz result = (vuntil - now) / USECS_PER_SEC; /* in seconds */
+
+			if (result <= (TimestampTz) password_expire_warning)
+				MyClientConnectionInfo.warning_message =
+						psprintf("your password will expire in %d day(s)", (int) (result / 86400));
+		}

Please consider localization of the warning message.

2. typo fix

a. `Controls how many time ...` should be `Controls how much time ...`.

b. `Sets how many time before password expire to emit ...` should be `Sets how much time before password expires to emit ...`
