What's about truncate FSM during WAL replay of main fork truncation record?
That would work, except that there's no WAL record for truncating the
main fork.
Whaddya mean there's no WAL record for that? smgrtruncate produces one.
Ooh, I didn't realize that!
Hmm. The smgrtuncate WAL record is generated after the file is
truncated, so there's still a small window there, where we can be left
with a truncated main fork, but no smgrtruncate record for it, and thus
the page of the FSM representing the truncated blocks doesn't get zeroed
at replay.
