Strange. I don't recall any 7.0.2 -> 7.0.3 changes that might affect
the frontend/backend protocol behavior. Did you compile 7.0.2 the same
way as 7.0.3?

You can, but in the long run it'd be more useful to figure out what's
going wrong. The above is not much info --- what are you doing when
this happens, and what if anything appears in the postmaster log?
