Oh, I have a theory about this: I bet your Homebrew installation
has a recent OpenLDAP version that only supplies libldap not libldap_r.
In that case, configure will still find libldap_r available and will
bind libpq to it, and you get the observed result. The configure
check is not sophisticated enough to realize that it's finding chunks
of two different OpenLDAP installations.
Not sure about a good fix. If we had a way to detect which library
file AC_CHECK_LIB finds, we could verify that libldap and libldap_r
come from the same directory ... but I don't think we have that.
