Looking at the patch we dont compress things > 1M anymore so I thought
maybe I was hitting that. But no luck there are only 39 rows where
the row size > 1M... With those 39 being about 22M each. Unless I
calculated something wrong. Oh and CLUSTER and VACUUM dont seem to
help.

BTW is there a "cooler" way to do this?
