Description
I recently transferred my app from Mysql to Postgres and found out that dumping the db using dumpdata on the Mysql-database returned in values like "is_superuser" : 1 for json. This is fine from a Mysql point of view, but bad for Postgres. Why? Well the Postgres backend uses a Boolen Field Type for Django's BooleanField whereas Mysql uses a TinyInt(?) with length 1. So I wasn't able to load the data in Postgres as it complained about wrong types (expecting boolean, got integer, or something like this...). It worked fine after converting 1 to "True" and 0 to "False"-

I ran into this myself once; IIRC it's only a problem in the JSON serializer, and only on deserialization; the XML serializer handles this fine, but the JSON one doesn't cast back from int
to bool
.

I've just run into this problem as well. It happens for yaml and xml formats as well. The problem is that Postgres dumps booleans as true/false and expects that format back with loaddata, otherwise it gives an error. Mysql dumps booleans as integers, but (at least version 5.0) is fine with inserting true/false as well.

This seems to be solved since that time.
The light switch can only be on or off. How do you propose it gets dumped? It can only be dumped in a way that's consistent with the database that is doing the dumping.
