Oracle and DB2 also offer an ability to parallelize queries across
nodes, so that you can query extremely large (multi-TB) data sets quickly.

They also all market multimaster replication.

PostgreSQL is an excellent small-to-reasonably-large-database RDBMS. If
you get into the 3-5 TB range and need fast access to all the data, or
if you need multi-master replication, you may need to look elsewhere,
depending on your application.
