20168	PostgreSQL specific example in documentation	Russell Keith-Magee	nobody	"The documentation on [https://docs.djangoproject.com/en/1.5/topics/db/managers/#adding-extra-manager-methods 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."	Cleanup/optimization	closed	Documentation	1.5	Normal	fixed			Accepted	0	0	0	0	1	0
