Upstream image centos/postgresql-96-centos7 is being used in product

When installing Fuseonline in our env, I found that the centos/postgresql-96-centos7 is being used, from my perspective, this is an upstream image, while a redhat image should be used. Our env did not allow the visit to upstream, so cannot install fuseoneline successfully.
