[ckan-dev] datastore: permission denied Schema public

Tue Mar 26 10:06:55 UTC 2013

Hallo Ralf,

We expect a permission error because there should be a connection that is not allowed to write. However, the check only works if the error message is in english, otherwise an exception is raised. 

There is an issue and a pull request at https://github.com/okfn/ckan/pull/642.

Until this fix is in the release branch, you could set the language of your postgres installation to english. 

Best wishes,
Dominik
