Thank you all.
In order not to open a new thread, (small clarification)
Don't be afraid to open a new thread. Indeed, a new topic (even if it is
minimal) deserves a new thread.
On the tutorial-agg page in the code example
SELECT city FROM weather WHERE temp_lo = max(temp_lo); WRONG
you need to add a comment before WRONG
If you consider that that query is correct and it fails in the "wrong" then you
made the point.
postgres-# select 1; wrong
ERROR: syntax error at or near "WRONG"
LINE 1: WRONG
^
However, the query is not correct and it fails before processing the second
statement (wrong) so it doesn't matter much in this case. Even after saying
that, I agree with you that this annotation without the comment characters
don't make much sense.
postgres=# SELECT city FROM weather WHERE temp_lo = max(temp_lo); WRONG
ERROR: aggregate functions are not allowed in WHERE
LINE 1: SELECT city FROM weather WHERE temp_lo = max(temp_lo);
^
