Why were you thinking of tracking it separately from PgStat_StatTabEntry? I think there's a good argument for starting to track some stats based on the relfilenode, rather the oid, because it'd allow us to track e.g. the number of writes for a relation too (we don't have the oid when writing out buffers). But that's a relatively large change... Greetings, Andres Freund
