You've encountered a psycopg2 AttributeError: "'module' object has no attribute 'extras'."

To address this issue, you can below step:

  1. Ensure that you are using the correct version of the psycopg2 library that includes the 'extras' module.
  2. Check your code to make sure you are importing the 'extras' module correctly. It should be something like `from psycopg2 import extras`.
  3. Verify the documentation for the version of psycopg2 you are using to confirm that the 'extras' module is still available and hasn't been deprecated or replaced by another module.
  4. If you recently updated psycopg2, check the release notes to see if there are any changes related to the 'extras' module.
  5. If the issue persists, consider reinstalling or upgrading psycopg2 to the latest version that supports the 'extras' module.

You can try, to explicitly import psycopg2.extras:

import psycopg2.extras
