Hmm, seems like a misfeature in pg_regress.  I guess adopting PGUSER
from the environment is a good thing to do in the "make installcheck"
case, but maybe it should drop it (along with the other environment
variables that could affect connections) in the "make check" case.
Peter, any thoughts about that?
