It doesn't appear there is a scalability issue here at all. Postgres can clearly do the same query in about the same time. We just have a case where MySQL happens to optimise it well and Postgres doesn't. Since we can trivially design cases that show the opposite I'm not worried too much. -- Simon Riggs www.2ndQuadrant.com PostgreSQL Training, Services and Support -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
