Your license, provided without charge, is here: http://www.postgresql.org/about/licence As to benchmarking... Please be sure to read up on the postgresql.conf settings - the default settings are designed to get the server to start on a reasonably wide range of platforms. It is assumed that the DBA will update these settings as appropriate for the platform and workload in use. Failure to do so will have serious performance implications. Also be sure you are familiar with VACUUM and ANALYZE and the effect they have on performance. Cheers, Steve
