The ones I know of that allow such a thing generally hard-wire the
location of the global config file at build time, rather than taking it
from an environment variable.  The env var approach seems weird, and a
tad inefficient (since you'd have to put such an env var into the global
.profile, meaning it propagates into every single process ever launched
on your system).  Also I think we have at least one global config file
already for libpq, and its location is hard-wired.
