Description (last modified by James Bennett)

Fixtures generated using an app running against mysql can't be imported by that same app if switched to run against postgresql. This appears to have to do with different handling of mixed case table/column names in django's drivers for the two databases.

Here's the error I get. The same error occurs regardless of fixture format. Note the case difference between spackle1_projecttemplate_subjectareas (from the exception) and spackle1_projecttemplate_subjectAreas (from the sql):

Loading 'spackle1/fixtures/spackle1' fixtures...
Installing xml fixture 'spackle1/fixtures/spackle1' from absolute path.
