That's interesting ... is there any possibility that the insertions were
attempting to insert values that matched a previously-existing primary
key value? I'm thinking there's no reason for the INSERT per se to be
touching nonexistent blocks, but if for some reason the pkey index still
had entries pointing at vanished rows (as it seems to) then the errors
could be coming from uniqueness checks attempting to fetch those rows to
see if they're live.

Hi,
There isn't possibility but close to 100% new inserted values were matched a previously-existing primary
key value.
The table is hand-made 'materialyzed view'-type statistic table which is getting recalculated via cron.
