> We need to disable the third input parameter in LEAD and LAG window functions. We should
support this syntax.
> LEAD(<expression>,1)
> LAG(<expression>,1)
> In both the functions above, the second parameter is the default offset value, use of
any other value must he handled and reported to user as error.
> Use of a third input parameter to both the functions must be disallowed.
