This Blog is a follow up uf one of my older Blogs and my Article at heise.de:

For RHEL 8 at its clones like AlmaLinux, CentOS, Oracle Linux and Rocky Linux i have written a shell script to automated recurring setups.
This is used for a cloud project using own virtual machines.
The script automates the steps i have described at my article at heise.de.
The script has an help opportunity, -h tell how to use it:
$ [[root@rocky ~]$ sh pg_setup.sh -h $ [[root@rocky ~]$ PostgreSQL Installation on AlmaLinux 8 / CentOS 8 / Oracle Linxu 8 / RHEL 8 / Rocky Linux 8 $ [[root@rocky ~]$ $ [[root@rocky ~]$ Usage: $ [[root@rocky ~]$ [OPTION] $ [[root@rocky ~]$ $ [[root@rocky ~]$ Options: $ [[root@rocky ~]$ -v Major Release of Postgresql (required) $ [[root@rocky ~]$ -t If the System is Primary / Single (p) or Secondary (s) in a Cluster (required) $ [[root@rocky ~]$ -h prints this help $ [[root@rocky ~]$
So the script supports any version of PostgreSQL supported by the PostgreSQL Community.
Required is an own volume or folder /pgdata or even per PostgreSQL version /pgdata/Major Releae, so for PostgreSQL 13 /pgdata/13/, if the the folder with the release number is not existing, it will be created.
The code of this script:

With this script it is possible to operate several PostgreSQL versions at the same time on the same machine.
The binary folder and $pgdata have the Major Releasenumber of PostgreSQL within the naming.
For PostgreSQL 13 $pgdata is /pgdata/13/data and the binaries are in /usr/pgsql-13/.
With this concept ist is possible to use pg_upgrade in copy mode and having the older version for a certain time in the background available for checks after upgrade.
In my upcoming blogs i will also provide scripst for scale up and down on memory and cpu parameters according to vCPU and Memory setting, pgpass and replication setup using repmgr.
