The motivation for a crash and restart cycle when a backend dies is that it might have corrupted shared memory on the way down; and we can't recover reliably except by reinitializing everything. But that doesn't apply to processes that don't touch shared memory. Currently, there's nothing to prevent a background worker that doesn't request shared memory access from touching shared memory anyway, but that's a separate bug. Previous to this commit, the coding in postmaster.c was inconsistent: an exit status other than 0 or 1 didn't provoke a crash-and-restart, but failure to release the postmaster child slot did. This change makes those cases consistent.
