저는 pg_parameter_status 함수에 대해 공부하고 있지만, 이 함수의 사용법과 결과값의 의미를 이해하지 못하고 있습니다.

pg_parameter_status 함수는 PostgreSQL 서버의 현재 상태를 반환하는 함수로, 여러 파라미터의 상태를 확인할 수 있습니다. 예를 들어, autovacuum가 활성화된 상태인지, 또는 max_connections의 현재 값이 무엇인지 확인할 수 있습니다.

저는 이 함수를 사용할 때, 몇 가지 부분에 대해 혼란을 느끼고 있습니다.

1. 이 함수는 어떤 파라미터의 상태만 반환할 수 있나요?
2. 각 파라미터의 상태는 어떻게 반환되나요? (예: 문자열, 숫자, 불리언 등)
3. 이 함수는 어떤 경우에 에러를 반환할까요?

제가 이해한 것과 다르게 작동하는 경우가 있는지, 아니면 제가 이해를 잘못한 것인지는 알려주시면 감사하겠습니다.
