help with generation_series in pg10

Hi,


In pg10 generation series doesn't work like in 9.5.
Ex. in 9.5:
z=# select generate_series(1, 10), generate_series(1, 5);
 generate_series | generate_series
-----------------+-----------------
               1 |               1
               2 |               2
               3 |               3
               4 |               4
               5 |               5
               6 |               1
               7 |               2
               8 |               3
               9 |               4
              10 |               5
(10 registros)


so, in version 10 the same sql show different result set.
z=# select generate_series(1, 10), generate_series(1,5);
 generate_series | generate_series
-----------------+-----------------
               1 |               1
               2 |               2
               3 |               3
               4 |               4
               5 |               5
               6 |
               7 |
               8 |
               9 |
              10 |
(10 registros)
