CREATE TABLE people( id serial PRIMARY KEY, name varchar NOT NULL );
INSERT INTO people(name) VALUES('Adam'), ('Adam'), ('Adam'), ('Bill'), ('Sam'), ('Joe'), ('Joe');
SELECT name, count(*), random() FROM people GROUP BY name;
I would expect this query to cause an error because of random(). I ran into this using an array produced by a subquery as a column in the select of an aggregate query, but I was able to boil it down to this contrived example. Shouldn't any expression that is not in the group by or an aggregate function be rejected?
