After i read PostgreSQL documentation, i found that pg_attribute contain "attrelid" that reference to pg_class oid. But after i look to "/src/include/catalog/pg_class.h" there is no member named "oid".
This what i trying to acomplish using "heap_getnext" function: if (((Form_pg_class) GETSTRUCT(ht_1)->oid) == ((Form_pg_attribute) GETSTRUCT(ht_2)->attrelid) { //do something } But its always failed in compile time since pg_class doesnt have "oid" member. And it seem "t_tableOid" was not pg_class oid since when i compare "t_tableOid" and "(Form_pg_attribute) GETSTRUCT(ht_2)->attrelid" nothing match. My question is, how to get "oid" from pg_class? or is there any other solution you can suggest?
