I think you mean the postmaster crashes?

I agree. This looks like a context problem: the StreamConnection
routine is calling elog() to report the error --- but elog expects
to be inside a running backend, not the postmaster process. Trying
to send to the client is no good, and trying to longjmp back to the
backend execution loop is even less good :-(
StreamConnection should probably just use perror to report the error
on stderr. There's no hope of telling the client about it...
