You're right that the statement is irrelevant in the context of what
a standby can or can't do, but what I'm worried about is that someone
will read it and believe that it represents the whole truth about
what read-only master transactions can do.  The previous wording was
also irrelevant to the context of a standby, and yet this whole thread
exists because somebody complained that it's an inaccurate description
of the restrictions on such a master transaction.  Well, it's still
inaccurate.
