I think EVERY is actively misleading, because it does *not* imply that
every input is TRUE. The spec says these aggregates should ignore
nulls, and so a true result only implies that there were no FALSE
inputs.
OTOH one could argue that the ignore-nulls behavior makes this not a
true analog of AND, either ...
