Exception Type: ProgrammingError at /review/13394/patchset/3680/delete
Exception Value: schema "datetime" does not exist


Last trace frame's local vars exploration revealed this:
'SELECT "codereview_patchset"."id", "codereview_patchset"."gae_key", "codereview_patchset"."gae_parent_ctype_id", "codereview_patchset"."gae_parent_id", "codereview_patchset"."gae_ancestry", "codereview_patchset"."issue_id", "codereview_patchset"."message", "codereview_patchset"."data", "codereview_patchset"."url", "codereview_patchset"."owner_id", "codereview_patchset"."created", "codereview_patchset"."modified", "codereview_patchset"."n_comments" FROM "codereview_patchset" WHERE "codereview_patchset"."issue_id" = 13394 AND created > datetime.datetime(2011, 11, 20, 11, 36, 4, 343046)'

I believe that it should look something like this:
'SELECT ... AND created > %s' % datetime.datetime(2011, 11, 20, 11, 36, 4, 343046)

I'm not sure where should I post this issue. I didn't find "rietveld/django/db/backends/util.py" in sources at rietveld.googlecode.com, therefore I posted it here.
