Description
Migrated issue, originally created by Anonymous
TypeError: execute() parameters must be strings
- reflecting tables from postgresql so column names are unicode strings
- using polymorphic loading
- convert_unicode=(True|False) had no effect
this patch fixes it for me but other places where reflected strings are used as kwarg keys will cause the same problem

we support unicode bind param keys, so the issue here lies elsewhere. small test cases are very helpful here since ill have to write one myself in order to locate.
