말씀하신대로 디렉토리경로까지 명령을 주어서 실행시킨 경우입니다.

su: warning: cannot change directory to /home/postgres: Permission denied

[1] 3181

bash$ FATAL: StreamServerPort: bind() failed: 허가 거부됨

Is another postmaster already running on that port?

If not, remove socket node (/tmp/.s.PGSQL.5432) and retry.

###지금 특히 이부분을 보니까 bind가 postgresql의 포트를 쓰고 있다는게

###검색 했을때 나왔던거 같거든요.../tmp/.s.PGSQL.5432가 보이지는 않지만

###있기때문에 mc를 써서라도 지워줘야 한다는데 맞는걸까요?...

지금 ps로 확인했을때 프로세스가 생성이 되었으니 실행이 된건지 궁금합니다...
