I have a vague feeling that you are right about that.  Perhaps the
concern was that under "make installcheck", pg_regress might be
using a build-tree copy of libpq rather than the one from the
system under test.  As long as we're just trying to ping the server,
that shouldn't matter too much I think ... unless we hit problems
with, say, a different default port number or socket path compiled into
one copy vs. the other?  That seems like it's probably a "so don't
do that" case, though.
