Hello !
And thanks to all, for answers.
Naturally, cron does not operate on DB tables and if I add/remove/change
a line in a control table dynamically, cron would not notice that ;-)
So I had to write a daemon, which acts on that table. This might happen
about ~5 - 20 seconds and cron is operates on minutes only.
An auto running stored procedure would solve the problem, if therewould be
a way to run this procedure on server startup automatically
[as it looks, write another daemon for this].
The usual notification from postgreSQL does not allow to write
an [own, better to evaluate] identifier in the syslog. This is
not a matter of the syslog daemon, its on the program which logs.
May be, I have just not found this.
Wished, my migration would a bit easier ;-)

cron is the standard way of scheduling reoccurring jobs on *nix systems.
It's preferable to having each daemon implement scheduling on its own.

Is this long running processes, i.e daemons, or is it scheduled processes?
For long running I would recommend writing a proper daemon.
For scheduled I'd recommend cron or at.

I'm pretty sure you can accomplish this in configuration if you're using
syslog-ng. Other syslog alternatives probably has similar possibilities.
