There you have it - "extended" means "holding wal". And as long as the
restart_lsn does not advance, checkpointer cannot free any wal beyond
that lsn. My first idea would be some long-running (or huge) transaction
which is in process (active or still being streamed). I'd recommend
looking into what the clients on these slots are doing.
