Thanks for reviewing. Regarding fast_forward, I think I had the idea
in mind that perhaps it should be exposed by
pg_get_wal_summarizer_state(), but I didn't actually implement that.
Thinking about it again, I think maybe it's fine to just remove it
from the shared memory state, as this should be a rare scenario in
practice. What is your opinion?
