Postgres and Redshift should not be considered equivalent. It's true that Redshift originated as a fork of Postgres 8, but Postgres has come a _long_ way since then and is quite different. On top of that, Redshift is columnar database, which is an entirely different animal than vanilla Postgres (or any other DBMS).
