Right, sorry. I thought there was some strength reduction going on there as well. Thanks for the various explanations, they address my concerns. I see that v2 applies over v1. I've verified performance improvements using 8 cores with my proposed pgbench -P benchmark, with a scale that fits in shared_buffers. It brings it most of the way, but not quite, up to the btree performance. I've marked this as ready for committer.
