Not so fast... logger just writes its arguments to syslog.  I don't
see any indication that it (portably) reads its standard input.
It's meant for use in shellscripts.  You could write:
... 2>&1 | while read i; do logger -p local1.warning -t 'PG ' -- "$i"; done

but syslog is pretty high-overhead already without starting up logger
on every message.  Maybe stderr messages are infrequent enough that
it doesn't matter.
