# Test Report ### Root cause From the documentation of pg, we know that when identifier is quoted, identifier is case sensitive, but Kylin use all upper-case, which make quoted identifier not identifiable by pg. At my patch, I disable all quote switch in `postgresql.xml`, so we cannot support reserved word as identifier, which is rare. ### Test Result After applied my patch, build from pg data source is fine, but pushdown is still not work, because it is caused by another patch from KYLIN-4068 . - Build Success   - Pushdown error ```sh 2020-06-18 10:53:12,241 INFO [Query
