So what Postgres was actually reading through was probably quite a lot less than 27Gb. It's probably hard to make a completely apples-to-apples comparison because the two databases are so different, but I don't think this one proves that PG is faster than Oracle. regards, tom lane -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
