Removal of the PinBufferForBlock() comment about the "persistence =
RELPERSISTENCE_PERMANENT" fallback started to feel like a loss.  I looked for
a way to re-add a comment about the fallback.
https://coverage.postgresql.org/src/backend/storage/buffer/bufmgr.c.gcov.html
shows no test coverage of that fallback, and I think the fallback is
unreachable.  Hence, I've removed the fallback in a separate commit.  I've
pushed that and your three patches.  Thanks.
