You can specify either --critical or --warning as a period of time, and it will report on failures within that period of time previous to the current time. Job failures are determined by a non-0 status in a job step record.

The `pgagent_jobs` test does not care if you specify a warning value greater than the critical value (indeed, I expect that if one used both at all, the warning would be much longer). So this new argument prevents the `range-warnbigtime` or `range-warnbigsize` failures from being triggered.

Assuming everyone is on board with this, I can commit it. Just let me know.

Thanks,
