Redshit vs Postgres

What Postgres & Redshift represent are are two different products for two very different problems. Postgres is good for small sets of transactional data like orders in a shopping cart system (less than 1TB). Redshift is good for big sets of data involving user behavior and clickstream analysis (greater than 1TB). I would not want to manage clickstream data on a single instance of Postgres nor would I want to manage an order system in Redshift.

Another data warhouse option is Cloudera Impala on them. You can use Apache Sqoop to pull the data out of Postgres and into HDFS.. Directly after, you can run SQL queries which will query the data in parallel (similar to redshift).
