3 months ago @mirecekparecek I think you are using the PostgreSQL packages provided by your distribution. Since the pgpool-II-pg15-extensions package are built for PostgreSQL 15 provided by the PostgreSQL community, which is installed in /usr/pgsql-15, it cannot be used with packages installed in other paths.
To work with your PostgreSQL packages, you need to install the pgpool extensions from source code.

Hello,
I was trying to install pgpool-recovery for online recovery. I followed the steps here: https://www.pgpool.net/docs/latest/en/html/example-replication-mode.html. But when I got to 8.3.5.5. Online Recovery I couldn't get it to install the extension.
Here are the errors I got:

Im using postgresql 15.6, rhel 9, pgpool-II version 4.2.17 (chichiriboshi) and I installed everything through package manager.
Thank you for your replies
