[check_postgres] nagios output for database_size + patch validate_range + new function

[Greg Sabino Mullane]

> * change validate_range to return also the warning unit and the
> critical unit when relevant.

Just to repeat for your next version of this patch. This change:

+	my ($warning, $critical, $wuom, $cuom) = validate_range

is not needed, as the subroutines calling validate_range do not use
$wuom or $cuom. However, we can calculate them inside of validate_range
as needed, and then refactor the bits that use them into an output routine.
