Redhat's version runs on (and I believe has optimizations for?) Linux ...
PgSQL runs on pretty much everything ...

Red Hat's version is not presently materially different from the
community PostgreSQL version.  In the future, the latest RH release
might be ahead of, behind, or different from the latest community
release at any given instant, due to vagaries of release cycles,
customer feature requests, or what have you.  But there is no intention
on either side (I fervently hope and believe) to cause a code fork
or long-term divergence.

Red Hat will provide commercial-grade support for PostgreSQL running on
RH Linux, and not for PG on any other system (AFAIK anyway).  But what
you're buying if you buy RHDB is that support, not a fundamentally
different product.
