In more detail, if smgrcachednblocks() returned InvalidBlockNumber for
any of the forks, we should give up the optimization at all since we
need to run a full scan anyway. On the other hand, if any of the
forks is smaller than the threshold, we still can use the optimization
when we know the accurate block number of all the forks.
Still, I prefer to use total block number of all forks since we anyway
visit the all forks. Is there any reason to exlucde forks other than
the main fork while we visit all of them already?
regards.
