RPMs for RHEL 6.8

Hi all,

On one secure server with no access to Repository I need to install packages that are needed to compile and install this python module "psycopg2".
In order to build and install the above mentioned python module I need; pg_config program and libpq headers that comes with "postgresql-devels".
The version that I'm trying to install of this module is 2.7, which is the last stable release, and it requires libpq that are version >= 9.1.0 .
I try installing the below RPMs ( downloaded from https://yum.postgresql.org/9.6/redhat/rhel-6.8-x86_64/ ), but even after that, the pg_config program is still not available:

- postgresql96-devel-9.6.2-2PGDG.rhel6.x86_64.rpm<https://yum.postgresql.org/9.6/redhat/rhel-6.8-x86_64/postgresql96-devel-9.6.2-2PGDG.rhel6.x86_64.rpm>

- postgresql96-libs-9.6.2-2PGDG.rhel6.x86_64.rpm<https://yum.postgresql.org/9.6/redhat/rhel-6.8-x86_64/postgresql96-libs-9.6.2-2PGDG.rhel6.x86_64.rpm>

- postgresql96-9.6.2-2PGDG.rhel6.x86_64.rpm<https://yum.postgresql.org/9.6/redhat/rhel-6.8-x86_64/postgresql96-9.6.2-2PGDG.rhel6.x86_64.rpm>

What else do I need to install ?

Best,
