Description
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.

Looks good in principle. However, it needs tests - if only so that it is easy to demonstrate that this approach will work across all supported backends.

I can't tell what this ticket is requesting from its description or its patch. Possibly it is fixed with enhanced expressions support in 1.8. If not, please reopen with more details.

wraps try/except around float(value) on convert_value
