I just re-read that thread, and it occurred to me that there is another
way to fix the problem: what we need is either for postmaster.opts to
not store the -D option at all, or for pg_ctl restart to override that
option with its freshly-derived idea of where the data directory is.
This would avoid my allergy to the idea of storing an absolute-ified
path, which I'm still down on because it would have failure modes of
its own.
