You can't do that.  In the first place it will dump core if PGDATA isn't
set, and in the second place it is not kosher to scribble on environment
values.

This is the wrong place to do it anyway.  It is necessary, sufficient,
and already done to do it in SetDataDir.

Could we not have FATAL here, please?

None of these are correct.  canonicalize_path is only intended for
directory names not file names.  (I think the same problem applies
to several of your GUC variable changes, too.)

As above.
