PostgreSQL specific example in documentation

The documentation on Custom manager objects uses an example for a custom method that opens a database cursor. However, the example uses a PostgreSQL-specific SQL dialect in the GROUP BY clause (the use of column numbers in the GROUP BY clause).
This is potentially confusing; using a more conventional GROUP BY clause referencing column names would be no less confusing for PostgreSQL users, but would make sense to those coming from other databases.
