Or even better, MaxBackendId can be set at the run time such as
postmaster's option. Also, it would be nice if we could monitor number
of backends currently running. Maybe we should have a new protocol for
this kind of puropose?
BTW, as I pointed out before, PostgreSQL will have serious problem
once hitting the MaxBackendId. My patches I proposed for this seem
still under discussion. I think we should solve the problem in the
next release in whatever way, however.
