You need to add "-l $LOGFILE" where log is wherever you want to write
the stderr+stdout from the postmaster to. Then it will return once
starting the server.

Not that I know of, but you can poll the server status using the same
pg_ctl command constructs as you're using already but with "status"
instead of "stop" or "start". pg_ctl (and hence ssh) will return 0 if
the server is running and 1 if the server is no running.

So you could try something like

while ssh $REMOTE pg_ctl -D $CLUSTER status
do
echo "Remote server still running - continuing to wait ..."
sleep 10
done

Hope this helps,
