You could doubtless do things with "pgcron" you cannot readily do with
cron, such as:

1. Expressing dependancies between jobs (e.g. - run A after running
B, don't start C if B is still running)

2. More specific time increments than cron offers (e.g. - heading
nearer to granularity of seconds)

3. An integrated way of logging what ran when (rather than either
stuffing logging code into each cron job or rummaging thru
cron logs)

4. You could use SQL queries to request information about jobs.
