pg_ctl seems to want to be told where "data" is:
pg_ctl stop [-W] [-s] [-D datadir]
I've been scattering data across spindles and mount points. The
doc speaks to this in the singular:
-D datadir
Specifies the file system location of the database files.
If this is omitted, the environment variable PGDATA is used.
Do I need to tell pg_ctl where all the data is or does it figure it out
internally?
