I need to upgrade pgpool2 from 3.7.20 to pgpool-II version 4.5
I am trying to test this in one of the local environement, there seems to be no option available in ubuntu to install older version of pgpool2.
Can someone guide on how can we install older version of pgpool2 in ubuntu and what are the ways to upgrade pgpool2?
Thanks in advance.
apt install pgpool2 — > its installing latest version
