-D points at the root of the data directory, a/k/a $PGDATA. This is
where postgresql.conf and some other installation-wide files live.
Individual databases are normally subdirectories under $PGDATA/base/,
but can be relocated elsewhere using the "alternate database location"
mechanism.

I think you also need "export PGDATA_ALTERNATE"; otherwise it's only a
local variable in that shell script.
