The "fast path" for well cached scans that don't do any I/O was accidentally coded in a way that could only be triggered by pg_prewarm's usage pattern, which starts out with a higher distance because of the flags it passes in. We want it to work for streaming sequential scans too, once that patch is committed. Adjust.
