문제가 생긴 이유

기존에 장고와 psql(postgresql) 연결을 위해 psycopg2 패키지를 이용하고 있었는데, 장고 공식 문서에서 "Support for psycopg2 is likely to be deprecated and removed at some point in the future."(https://docs.djangoproject.com/en/5.1/ref/databases/#postgresql-notes)라고 안내하고 있기 때문에 psycopg2를 uninstall하고 psycopg를 install하니 발생한 문제입니다.

현재 psycopg 패키지를 성공적으로 설치한 상태입니다.
