You've encountered a psycopg2 AttributeError: "'module' object has no attribute 'extras'."
To address this issue, you can below step:
- Ensure that you are using the correct version of the psycopg2 library that includes the 'extras' module.
- Check your code to make sure you are importing the 'extras' module correctly. It should be something like `from psycopg2 import extras`.
- 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.
- If you recently updated psycopg2, check the release notes to see if there are any changes related to the 'extras' module.
- 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
