Hmm, so there's a more detailed discussion on GitHub [1] and from the looks of things, this package split was intended to work issues with SSL libraries. Unfortunately they don't discuss a resolution to potential clobbering issues, likely because there isn't one. I've started a discussion on the mailing list [2] but at this time it seems we might be better off just requiring the installation of libpq once again. I'm going to abandon this until we have a better idea of how to approach this.
