The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/15/tutorial-agg.html Description:
Near the end of Chapter 2.7 Aggregate Functions of the documentation, the command FILTER is introduced. The full query is SELECT city, max(temp_lo), count(*) FILTER (WHERE temp_lo < 30) FROM weather GROUP BY city HAVING max(temp_lo) < 40; and the output shows a count value of 5. This is an error. In total we only have 3 rows in the table so far. Furthermore, none of the rows have temp_lo < 30. If I'm not mistaken, the count value should be 0. Thanks, Jimmy
