[pgpool-general: 5290] Connections to backends

[Tema Zelikin]

Hello.

I have a following configuration:

3 backends with replication in master-slave mode.
2 pgpools with delegate_IP and watchdog, with weights of backends as
following:
master = 1
both slaves = 0

My understanding is that pgpool shouldnt make requests to backend nodes with weight of 0.

The question is why does pgpool establishes a connections to those nodes?

Second question, something i couldn't understand from reading a documentation: why does number of connections to backends is much more than number of connections to frontend?
