Hello

After going through the installation of the latest PgPool-II v4.6.2 on
Rocky Linux v10.1, I noticed that PgPooll-II required me to install
EPEL repository to satisfy dependencies.

After adding PgPool RPM repo for RHEL/RL 10 as per docs I was getting
following during install:
dnf install --disablerepo="*" --enablerepo="pgpool46" pgpool-II-pg18

Last metadata expiration check: 0:08:48 ago on Thu 27 Nov 2025 10:18:17 AM EST.
Error:
 Problem: conflicting requests
  - nothing provides libmemcached.so.11()(64bit) needed by
pgpool-II-pg18-4.6.4-1pgdg.rhel10.x86_64 from pgpool46
(try to add '--skip-broken' to skip uninstallable packages or
'--nobest' to use not only best candidate packages)

The package that contains this library is "libmemcached-awesome",
which I was not able to find in any of the OS provided repositories
The solution was to install EPEL repo following directions as per:
https://docs.fedoraproject.org/en-US/epel/getting-started/

Once the EPEL repo was installed, I was able to install pgpool.
Here is the list of relevant packages after the install:

dnf list --installed | grep -i -E "^(postgres|pgpool|pg|epel)+.*"

It may be a good idea to add this to the documentation (this whole
section could use update tbh):
