This sounds an awful lot like it would have to scan through the list of
existing connections, which I wanted to avoid.
Or maybe we could maintain a separate list of "reserved" connections,
i.e. ones that were created when we were at max_connections -
ReservedBackends? We could quickly look through that list to see how
many of which we have allowed. Not sure if that's practical, though.
