Subject: [PATCH v4] Fix missing tab completion in "ALTER DEFAULT PRIVILEGES"
GRANT, REVOKE and FOR USER keyword was not displayed in tab completion of "ALTER DEFAULT PRIVILEGES" like the below statements:
ALTER DEFAULT PRIVILEGES GRANT INSERT ON tables TO PUBLIC;
ALTER DEFAULT PRIVILEGES REVOKE INSERT ON tables FROM PUBLIC;
ALTER DEFAULT PRIVILEGES FOR USER testdba REVOKE INSERT ON tables FROM testdba;
"GRANT OPTION OPTION" was not displayed in tab completion of "ALTER DEFAULT PRIVILEGES REVOKE " like in below statement:
ALTER DEFAULT PRIVILEGES REVOKE GRANT OPTION FOR SELECT ON tables FROM testdba;
"WITH GRANT OPTION" was not completed in tab completion of "ALTER DEFAULT PRIVILEGES ... GRANT ... to role" like in below statement:
ALTER DEFAULT PRIVILEGES FOR ROLE testdba1 GRANT ALL ON tables to testdba2 WITH GRANT OPTION;
