-1. Updating ps_status is expensive, seriously so on some platforms.
We could likely get away with tracking progress in pg_stat_activity
though.
However, this just reminds me that tracking intrastatement progress in
pg_stat_activity has been discussed before and not much has happened.
Let's please not have a quick kluge that just addresses CLUSTER and not
any of the other aspects of that problem.
