Hmmm... Missed that!
I think you are looking for the feature that was introduced in
PostgreSQL 9.1 where you could have a non-group-by column in the select
list, but only if the group-by has a pkey to identify the actual row.

(Search for GROUP BY)

Thank you for yuor suggestion, Robins. Unfortunately, it does not work;
this returns:
1787 "Toomyvara" 0.5
1787 "Toomevara" 0.4
1188 "Toonybara" 0.4
because while column "no" is identical, "name" isn't and you're
grouping by both of them.
