No. Hmm...
I think the basic problem is that two versioned libs exist (4, 5), even though no versioning is provided, nor necessary. The versioning is only required as soon as backward compatibility is broken by the new lib version. This isn't the case, so libpq4 should never have been created in the first place, rather just a libpq. Since libpq4 exists now, I think the right thing to do would be to use this name until a new lib version breaks backward compatibility. Then it's time for a libpq>4 and the DLL in it should start to use versioning, too.
