I don't see any way to accurately find the data directory location.
Reading postgresql.conf is one way, but what if they set data_directory
on the command line using postmaster -o? Is reading postgresql.conf
from pg_ctl without a parser really accurate? Shame we can't attach and
do "SHOW data_directory" on a backend.
