In ps status you mean?  I don't think we are prepared to require ps
status functionality to let the system start up... we'd lose a number
of supported platforms that way.

In the case of an actual crash and restart, postgres should come back up
without help.  However, the situation here is not a crash, it is
incomplete admin intervention.  I don't think that expecting the admin
to complete his intervention is the same thing as manual crash recovery.
I especially don't think that we should second-guess what the admin
wants us to do by auto-killing backends that are still serving clients.
