Hmm.  pqStrerror is defined in libpgport (which is linked into the
backend) as well as libpq.  ISTM that libpq should not be linked with
-Wl,-bI:../../../src/backend/postgres.imp, since it's not intended to
be loaded into the backend.  Without having looked at the code, I'm
wondering if the AIX makefiles stick that option into LDFLAGS_SL rather
than someplace more restricted.
