No, I don't think so. During a system shutdown, init will deliver
SIGTERM to all the backends as well as the postmaster, so the backends
will die quite handily without the postmaster needing to give them any
additional push. We should not change to a less-safe default behavior
when there is no need to.

Or we could just switch over to syslog as the standard log
destination...

Agreed.

Perhaps the postmaster should have a '-u userid' option and do a
setuid() call ... though I don't know whether this will be materially
more portable than invoking su from a script.
