Hmm. The wording of the warning doesn't seem to really indicate
the full scope of the limitation. Any a standby (warm or hot)
maintained by WAL file copying would also be affected (i.e.,
streaming replication as the WAL delivery mechanism is irrelevant),
and you also have problems after a database crash or PANIC. I'm
not sure how to state that concisely, though.
