    Does this mean it will not handle multi AND/OR, between, in etc?

    In such cases shall we fold these predicate and add: always false?
    In machine generated queries these patterns might be encountered.

    This will also update type of expression if needed, correct? e.g. pushing 
86L to column of type int. I think thats probably ok. Can you add a comment for 
that.
