Postgres has finally come to RDS!  Want to know how these instances stack up on a naive pgbench test?

Below is a table of simple pgbench results taken over a 60 second period.   All RDS instances were launched into us-east-1a, and pgbench (9.4devel) was run from an m2.4xlarge in us-east-1a as well.
