Oh, and Theory 3: see if restarting your postgresql server fixes it.
If you didn't restart then the old openldap libraries are probably
still in the server's address space. I'm not sure exactly how that
might lead to this symptom, but it sure looks like your libldap and
liblber are out of sync somehow.
