# 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
