Hi, Thanks a lot for benchmarking this. Just a note to say that the "Allow direct lookups of AppendRelInfo by child relid" patch is already in master. It's much more relevant to be testing with master than pg11. This patch is not intended for pg11. -- David Rowley http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
