The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/15/tutorial-agg.html
Description:
Hello: I am working through the tutorial and the Doc page says the row count
is 5 but my results show 0 records. Of course, I may be doing something
wrong, too:
jwjwj=# SELECT city, max(temp_lo), count(*) FILTER (WHERE temp_lo < 30)
FROM weather
GROUP BY city
HAVING max(temp_lo) < 40;
city | max | count
---------+-----+-------
Hayward | 37 | 0
(1 row)
