+ * If {@link ArrayAnyComparisonExpression} is of the form:

+ * <pre>
+ * COL = ANY(ARR)
+ * </pre>
+ *
+ * then we can extract the scan ranges for the COL, given COL is a PK
column. This syntactical

of following IN

+ * COL IN (VAL1, VAL2, ... VALN)
Review Comment:
I don't think we can use this for RVC list like (COL1, COL2) IN (
(val11,val12), (val21, val22))
