How is this different from #16250? Doesn't r16520 fix the issue?

NB: edited description to fix formatting.

I suspect the OP is using Django 1.3 released on March (or the Django 1.3.X branch) and got psycopg2 2.4.2 (released) on June installed.

We fixed compatibility with the changes introduced in psycopg2 2.4.2 ony in trunk for what will become Django 1.4.
Is it is usual with open source projects with a release policy, we don't introduce changes to add compatibility with other software released after our releases, not even in the 1.3.X bug-fix only branch.

Possible solution for the OP would be to

  • Keep using 1.3 (or 1.3.X) and use psycopg2 <= 2.4.1
  • Keep pyscopg2 2.4.2 and switch django to in-development Django trunk
