Re: RHEL certified repo provided PostgreSQL Major Version Upgrade.

Hi Obi,

Just to update you, we are not using the PGDG community that provides
Postgres.

And the major difference between the PGDG community provided Postgres and
RHEL provided Postgres is the binary files are installed in different
location.

in PGDG Postgres it is installed under `/usr/pgsql-16/bin` whereas in RHEL
Postgres it gets installed under `/usr/bin`.

hence we can't use the command you suggested.

Regards,
Sameer Malve.
