I use a customized parser to override the createCall method of
SqlAbstractParserImpl to activate my OperatorTable.

I am a little curious. [~hhlai1990] - isn't there already a way to use custom
operator table without changing the parser? I recall that we can resolve any
operators if the way we use validator is appropriate, no matter built-in or not
built-in the operator is. (Sorry maybe I missed some contexts here)
