Unfortunately yes, the compression options and existing parallel code in Oracle means that at the moment IMHO Oracle performs better than PG at that scale.<p>There are multi petabyte Oracle RAC instances in existence, while on the other hand a 10TB+ PG is very large.<p>This is a first step in closing that gap. Some form of compression on block level would really help as well. For analytics columnar support will be needed to, and an in-memory option would be nice too.
