[PR #399/bbaee4fe backport][stable-1] Add missing psycopg2.extras import

[patchback]

This is a backport of PR #399 as merged into main (bbaee4f).

SUMMARY

On some of our systems the postgresql_query task failed with the following error:

AttributeError: module 'psycopg2' has no attribute 'extras'

Applying the patch from this commit fixed the issue for me on those systems. This was previously reported in issue #283. However now that some time has passed, I am unable to reproduce the issue on our newer systems.

In any case, this is still a mistake that could cause problems in the future, so I think it would be better to fix it.

The reason that this mistake is not causing any actual errors in normal situations is because of how the python import system functions: All of the entrypoints (all the source files under plugins/modules) have an import for psycopg2.extras. This causes extras to be available on psycopg2 for any code (in any module) that executes after that import statement, such as the function bodies in module_utils/postgres.py.
