This is exactly why I think the whole proposal is a nonstarter.  It is
necessarily pushing more complexity into the postmaster, which means
an overall reduction in system reliability.  There are some things
I'm willing to accept extra postmaster complexity for, but I say again
that not one single one of the arguments made in this thread are
convincing reasons to take that risk.
