Yes, I read that FAQ. But I could also clearly observe that if it reaches
"num_init_children" concurrent sessions, then it is not even allowing
existing/already connected users a chance to disconnect, though. So, it
becomes like a deadlock situation.

In order to set the right value for "num_init_children", we want to find out
the *maximum connection* reached at any given timeframe from pgpool log, in
case if we decide to increase "num_init_children" value.  Is it possible to
determine this information from pgpool?
