Yeah.  The reason it's reserved is that per spec, USER is equivalent to
CURRENT_USER, ie it's a built-in function that returns the current login
name.  So anytime you forgot and wrote
    select user from ...
instead of
    select "user" from ...
it would still work and you'd get mysteriously wrong output.  You
don't want to go there.
