Should theoretically be OK --- all of those pages were overwritten with
valid data from WAL playback. What you need to worry about more is
whether the crash lost any pages that were *not* restored from the log
(because they hadn't been modified lately). I'd suggest running a
pg_dump to see if any bad data turns up.
