trying to commit

features and restrictions are:
 - grant and revoke on objects : table, view, sequence, column
 - cascade mode is not supported for revoke (only default mode 'restrict' is supported)
 - "ALL xxxxx IN SCHEMA" is not supported
 - alter table with "owner to" for table object
 - return error code 1 if files are different
 - 'REVOKE ALL(untildate) ON TABLE privatekeys FROM PUBLIC;' is not supported in state. User need to add a space character betwwen ALL and bracket. Syntax seems invalid.
