I agree with you. Maybe crash safety would require some care in cases where autovacuum runs very frequently, so that the overhead isn't too high. But overall, non-crash-safe information that drives autovacuum is penny wise, pound foolish. I'm sure that it doesn't matter that much most of the time, but there are probably workloads and use cases where it causes significant and persistent problems. That's not the right trade-off IMV. -- Peter Geoghegan
