마지막 설치 시도에서도 postgresql 오류가 발생했습니다

2020-05-27 21:27:14.782 UTC [64] FATAL:  could not map anonymous shared memory:                                                     Cannot allocate memory
2020-05-27 21:27:14.782 UTC [64] HINT:  This error usually means that PostgreSQL's request for a shared memory segment exceeded available memory, swap space, or                                                     huge pages. To reduce the request size (currently 1399185408 bytes), reduce Pos                                                    tgreSQL's shared memory usage, perhaps by reducing shared_buffers or max_connect                                                    ions.
