[ shrug... ]  So?  There isn't going to be any way that
random-app-using-libpq is going to have a way to tell the user what the
underlying copy of libpq is using for this default --- adding a call for
that will be nothing more nor less than a waste of code space.  You'd be
best off running strings(1) over the libpq.so file when the question
comes up.
