I don't have an objection to providing an example. I wasn't terribly
impressed with Simon's version, but maybe we can do better. I think
it should be concrete, not partly abstract; and likely it needs to be
with \if not the variable proper.

I don't recall anyone questioning whether PQserverVersion() would work
with older servers. Being able to tell what version the server is is
sort of the point, no? If there were a restriction on what it would
work with, I would agree that that needs to be documented. But I
don't think "yes, it really works" is a helpful use of documentation
space.
