Just you need to go through the release notes of both the versions and validate them accordingly. Upon my experience that's the best known method to validate things. Again it depends whether you wanted to do a data validation of the admin level validation ( considering only the file system level changes or binary upgrades if any). Pg_upgrade should infact take care of the upgrade. That's why it's better to do a pg_upgrade check before doing actual upgrade.. hope this helps.

Subject: Validation of db post minor upgradation
Hi all,
Is there any validation to be performed in database after upgrading postgres version from 15.2 to 15.6 ?
I am using openshift env.
