Summary
I’m working on this, and I was thinking that I could extend the pretty printer’s behavior.
It already handles grouping for binary and prefix-unary expressions.
We extends the same support to postfix expressions such as
IS NULLandIS NOT NULL, adding parentheses when required by the grammar.(field IN (1, 2)) IS NULL
