You can set up the equivalent of Oracle Standby if you wish, using PITR.
Other methods of Replication for resilience are possible, such as Slony.

pgcluster implements something similar to Oracle RAC, but I have not
seen a production installation of this, though this may exist in Japan?

pgpool can be used to load balance across multiple servers, if that was
your requirement for RAC.
