Hmmm... if the number of rows is actually accurate (2M out of 10M in the
last 30 days) then a Seq Scan seems like a good plan to me. If the
numbers aren't accurate, it's time to run a VACUUM ANALYZE.
Regardless, if you're actually querying for 2M recordsets, you'd better
throw some hardware at the problem, and learn the .conf parameters.
