I was also slightly dubious about it. However, we do still need to solve the
problem that the patch addressed. Buildfarm members platypus and cuckoo are
currently failing because dblink is picking up the wrong libpq (and it
appears that incorrect libraries are also being picked up in the ecpg
libraries, although this isn't causing a buildfarm failure.)

Alternatively, if we can't say --with-libraries=/foo/bar when /foo/bar
contains possibly conflicting libraries, that should be tested for at
configure time.
