Known Issues
- using encoding different than UTF-8 (unicode) causes errors
- rules are not imported
- trigger functions are grouped with standard functions
- dependencies are imported only from views
- tables and views with no comments, but containing column level comments are not correctly imported. Add a table level comment to solve the issue
