The backend supports all kinds of things.  We have redundant compatibility
syntax for Oracle, MS-SQL, we even broke backward compatibility to support
MySQL, and we have confused users for years with MS Access compatibility.
None of these are standards.

Meanwhile, this new syntax is a tiny change, completely compatible, and
actually makes more sense rather than less from an overall consistency
point of view.  (If the change were allowing leaving off the parentheses
things would have been completely different.)

This way it was the least amount of change and the rules could be reused
for session_user and such.
