Since we haven't yet come up with a reasonable way of machine-editing
postgresql.conf, this seems like a fairly serious objection to getting
rid of recovery.conf.  I wonder if there's a way we can work around

*thinks a little*

What if we modified pg_ctl to allow passing configuration parameters
through to postmaster, so you could do something like this:

pg_ctl start -c work_mem=8MB -c recovery_target_time='...'

Would that meet pgpool's needs?

(Sadly pg_ctl -c means something else right now, so we'd probably have
to pick another option name, but you get the idea.)
