OK, that's a good use-case to warrant barrelling ahead with improving
pg_ctl for config-only installs. What releases do we want to apply that
patch to allow postgres to dump config values and have pg_ctl use them?
This patch is required for old/new installs for pg_upgrade to work.
Once we decide that, I will work on the pg_upgrade code to use this as
well. pg_upgrade will use the new pg_ctl but it also needs to find the
data directory via the postgres binary.
