We recently pushed to our production environment a feature that involved summing (with django.db.models.Sum) over CharField entries containing numeric text. It ended up not working correctly since the postgresql SUM function can't handle textual arguments, whereas sqlite's apparently can.
A nice feature that might have saved us the trouble would be to emit warnings when running an aggregation function with types that don't work with all of the db backends. Any objections to me filing a feature request for this? -- You received this message because you are subscribed to the Google Groups "Django developers" group.
