I agree --- we could answer this by adding some readout capability
(think "show datadir") rather than by taking away functionality.
Personally I rely quite a lot on setting PGDATA to keep straight which
installation I'm currently working with, so I'm not going to be happy
with a redesign that eliminates that variable without providing an
adequate substitute :-(
