Try disabling replication on that table and clustering the table and
then re-enabling replication. I would have to double check but I think
check_postgres --action=bloat only checks for dead space, not usable
space, so you could actually still have bloat, just bloat that is usable.
Alternatively you could disable replication on that table, truncate the
table, and then re-enable replication for that table. A concern would be
is that it is a large table regardless, which means you are going to
hold open a transaction to refill it.
