Because it would give a false promise of working. If I put a date in
my db, I'm expecting a date to come out: any other result is an error.
The hstore adapter is documented to take strings mapping: results with
any other mapping is undefined. A better behaviour could be to
explicitly raise an explicit exception, but it would be less efficient
than trusting the user he is using the adapter as documented (see
HstoreAdapter._getquoted_9(): we adapt the dict.values() list, not
iterate on each values).
If writing a date in and reading a string out is enough for your
application, you can easily write your own specialized hstore adapter
based on the code in extras.py.

No, I think adaptation is currently only global. No, I don't like this
asymmetry with typecasting either.
