RDS takes care of 1/3 to 1/2 of the configurations, particularly around hardware related options. However, since postgres uses MVCC, it has a lot of tuning options around autovacuum and replication that impact performance. This is even more true if you have access patterns that don't take into account postgres' MVCC (are you updating 10%+ of large tables daily, triggering autovacuums?) but which would be fine with mysql
