"ipsql"? Did you mean psql? If not, I'm clueless what client software
you are talking about.

Hm. The backend should shut down when it's informed by the kernel that
the client connection socket has been closed. We have heard about
problems of this sort before, but AFAIR all the identifiable cases
have turned out to trace to client misbehavior, namely failure to close
a connection that the client isn't using anymore. What does "netstat"
show about the state of the connections? What is your client code
exactly?
