Yeah, we can do that for slotsync path but it should be okay to keep
at LOG level for logical replication/decoding path as there it
shouldn't hit as often as in slotsync path. But OTH, there is a
argument that it can be DEBUG for logical replication/decoding path as
well. From my experience, I can tell that these messages have been
helpful in finding BF failures and debugging bugs from user reports,
so there is value in keeping them at LOG level.
