That would be required to make pg_regress run as far as its own
facilities are concerned.  But I think Alvaro is worried about something
at a higher level: the regression test process as a whole has some
directory layout assumptions built into it, particularly in regards
to where to find .so's.  If we don't have a workable solution for that
it's not really going to help to change pg_regress like this.
