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

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

Some kind of visual interaction between psql, the pager, and your terminal?

I'm betting there's something broken about your pager
settings, because 21 is as far as the display would get
in a standard-height (24 lines) xterm window. When I do
this I see
...
19
20
21
--More--
Since you're not getting a prompt but just the subsequent
\timing output, it seems that the rest of the output went
into the bit bucket, which psql would certainly never do
on its own. But a malfunctioning pager might act that way.
