Moving from Oracle to Postgres, what should I know?
pg_wait_sampling together with pg_stat_statements gets you nearer to Oracle's ASH/AWR capabilities. PoWA can integrate that (and other interesting extensions) to generate some nice reports.

[RDS] Huge spikes in CPU Usage, but the Freeable Memory remains high. How do I configure my DB to use more memory?
Another Another source of high CPU could be wait events. There are no built-in tools in Postgres to monitor them (unless RDS provides some). The approach I'd take on a "regular" Postgres installation is to sample the content of pg_stat_activity and then later analyze that after spikes have occurred. There are several extensions that already provide this, e.g. pg_profile or pg_wait_sampling or pgsentinel
