It looks the call to mark_function_volatile() is removed in this case. I think
we still need it, otherwise we won't know if the command contains a volatile
function. (see check_command_publishable().)

If the second alter-table is no-op in terms of deparsing, the dumped result of
origin command and that of re-formed command will be different. This seems to be
because `conislocal` column of pg_constraint has different values. (After the
second alter-table, its value is changed from false to true.)
