Our workload is "aggregations/drill downs/roll ups/... " (= OLAP) but we need OLTP like performance i.e. our users are not keen to wait more than several seconds for the result. Greenplum or Postgres + Fusion IO can deliver this performance for us. -- Ondrej Ivanic (ondrej.ivanic@xxxxxxxxx) -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
