andI’ve updated the patch as you suggests. 

1) This change is not required as it is not supported for pg_dumpall

2) I felt pg_dump will include the cascade option for plain format and
pg_restore will include the cascade option from pg_restore for other
formats. If my understanding is correct, should we document this?

3) This change is not required

destroyPQExpBuffer(ftStmt);
                                                        pg_free(dropStmtOrig);
                                                }
+
                                        }

4) Is it possible to add a few tests for this?
