A question about generate_series

Hi team,

when I use the generate_series,as you can see

(Fedora Linux 37, PGSQL 15.3)

postgres=# SELECT x FROM generate_series(1, 25, 1) As x;
 x  
----
  1
  2
  3
  4
  5
  6
  7
  8
  9
 10
 11
 12
 13
 14
 15
 16
 17
 18
 19
 20
 21
Time: 0.518 ms

My question is, why postgres didn't print the 22 to 25?

Can someone give some advice?

Thanks in advance!

Yours,

Wen Yi
