Hi, examine_attribute() function accept Relation type argument, and extract attribute from it.
For more granularity, I think passing Form_pg_attribute to examine_attribute() function rather than passing Relation will be more relevant & makes it simple to understand. Thinking to change examine_attribute as, - examine_attribute(Relation onerel, int attnum, Node *index_expr) +examine_attribute(Form_pg_attribute attr, Node *index_expr) I think there wont any loss or gain except little optimization of function call stack space. Thoughts? comments? Please have look attached patch. Regards, Amul Sul
