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.

Sorry Maxim,
Trying to follow along here: Are you say the inserted record DO or DO
NOT match previously existing key values.
