Odd. The postmaster log fragment you show contains no indication that
there's anything wrong, AFAICS. Even odder, there's no complaint about
an unexpected client disconnect, so it would seem that the client side
sent a deliberate disconnect (X) command.

One idea that comes to mind is that perhaps either the client or server
side is running under "ulimit" restrictions that kick in right here.
That doesn't seem to explain your symptoms, but some related idea might
be the right answer.

It might be possible to learn something by attaching to the backend
process with gdb and setting a breakpoint at proc_exit, so you could
see where it's being called from. If it's not reacting to an "X"
command then we'd learn what is making it exit.
