with_scope and :group option fails for PostgreSQL

Reported by CancelProfileIsBroken | February 28th, 2009 @ 05:10 PM | in 3.x

We fail on this using PostgresQL, due to rules on what the SELECT clause contains. Passes in MySQL/SQLite3.

def test_scoped_find_with_group developers = Developer.with_scope(:find => { :group => 'salary' }) do


end assert_equal 4, developers.size end

=> ActiveRecord::StatementInvalid: PGError: ERROR: column "" must appear in the GROUP BY clause or be used in an aggregate function : SELECT * FROM "developers" GROUP BY salary

Diff with the failing test attached. No patch yet.
