10932	Allow Min() on CharFields on postgres	Guillermo Gutiérrez	Greg Wogan-Browne	"Ticket #3566 (features aggregation for ORM) adds method convert_value which fall into ""float(value)"" and then, does not allow to apply Min, Max, etc, to CharFields. sqlite backend overwrites (in DatabaseOperations) this and returns value instead of float(value), but postgres backend does not overwrite this method.
I'll attach an improvable workaround on this.
