Not shutdown worker command when db is not accessible (feature)

[Logioniz]

When the administrator shuts down the database, then need to restart the command worker after the start of the database.

Maybe add a key in the command line that the worker had not completed its work when the database is not available.

I'm afraid this feature request is too imprecise to be considered. What exactly is that command-line "key" supposed to do?

I know zero services which need to restart when restart db.

I believe code must look like something like that, but need correctly detect problem of connect to db:

$ git diff
diff --git a/lib/Minion/Command/minion/worker.pm b/lib/Minion/Command/minion/worker.pm

I'm open to accepting a good patch for this, but it needs to be well thought out and take all the different backends into account.
