My patch doesn't loose the option, it's never been passed on anyway:

 opt_with_grant:  WITH GRANT OPTION
                                {
                                        mmerror(ET_ERROR, "WITH GRANT OPTION is not supported.  Only relation owners can
 set privileges");
                                 }
                | /*EMPTY*/
                ;

The existing code in ecpg/preproc/preproc.y to handle the WITH option
simply throws an error and aborts the processing... The patch below
prevents the segfault and also passes on the WITH option to the
backend, probably a better fix.
