That's right. You'll have, from pgpool, a maximum of
num_init_children*max_pool connections (IOW, 128 with your connections).
Out of these 128 connections, only 32 will be active at one time.
I'll try to explain it another way. When client C1 connects to
PostgreSQL via pgpool, it will use one of the four possible connections
of a pooler process.
