Document incompatibility of comparison expressions with VARIADIC array arguments
COALESCE, GREATEST and LEAST all look like functions taking variable numbers of arguments, but in fact they are not functions, and so VARIADIC array arguments don't work with them. Add a note to the docs explaining this fact. The consensus is not to try to make this work, but just to document the limitation.
