Yeah, the BackendStartup change is 100% wrong; it is replacing
perfectly good code that recovers correctly with bad code that
will take down the postmaster (not a backend child!) on OOM.

By and large I don't like anything about this patch.  You could
get the same results (i.e. elog(ERROR) on OOM) by replacing the
malloc calls with pallocs.
