Sorry for late reply. I am blocked by other things recently.
For this pr, I tried to keep consistent with pgsql for ansi mode, but failed.
For example:
Pgsql does not treat '1' as a string, but spark will treat '1' as string at first.
So, It is easy to cast string to double when comparing with Integer type, but it is difficult to keep consistent with pgsql.
