자체 호스팅 사용자를 위한 PostgreSQL 18 업데이트

뉴스 및 이벤트 공지사항

이것은 우리가 지원하지 않는 부분이므로 프로세스를 테스트해 보시는 것을 권장합니다. 다만, 업그레이드를 지시하기만 하면 문제가 없을 가능성이 높습니다.

표준 설치와 이중 컨테이너 환경에서 PostgreSQL 18을 설치했는데 아무런 문제 없이 잘 진행되었습니다. 쉬운 설명을 제공해 주신 @chrisr 님과 팀에 다시 한번 감사드립니다.

Cloudflare CDN 뒤에서 R2 업로드/백업 버킷을 사용하는 이중 컨테이너 구성을 위해 제가 사용한 단계는 다음과 같습니다:

1단계: 디스크 정리

# 사용하지 않는 docker 데이터 모두 삭제
docker system prune -a -f

# 오래된 로그와 apt 캐시 정리
journalctl --vacuum-time=2d
apt-get clean
apt-get autoremove -y

# 데이터베이스 크기 확인
du -sh /var/discourse/shared/data/postgres_data*

# 새로 확보된 여유 공간 확인
df -h -x tmpfs -x devtmpfs

2단계: 유지보수 및 백업

  1. Cloudflare 유지보수 페이지를 편집하여 15~20분간의 시스템 유지보수 업데이트라고 표시합니다(이 정도 시간이 걸리지는 않을 수 있지만, 안전을 위해 여유를 두는 것이 좋습니다!). 그리고 재로드 타이머를 30초 정도로 설정합니다. 유지보수 페이지를 표시하도록 Cloudflare 워커 라우트를 활성화합니다.

  1. 명령줄을 통해 백업을 트리거합니다:
cd /var/discourse
./launcher enter web_only
discourse backup
exit
  1. Cloudflare R2 대시보드에 로그인하여 백업 폴더를 확인하고 백업 파일이 성공적으로 업로드되었는지 검증합니다

3단계: 안전 종료

  1. 먼저 활성 연결을 종료하기 위해 웹 컨테이너를 멈추고, 그 다음 데이터베이스 컨테이너를 멈춥니다:
cd /var/discourse
./launcher stop web_only
./launcher stop data
  1. PostgreSQL이 올바르게 종료되었는지 확인합니다:
tail -n 20 shared/data/log/var-log/postgres/current

4단계: 업그레이드 리빌드

다음 명령어를 순서대로 실행합니다:

./launcher rebuild data # postgresql 18 덤프, 마이그레이션 및 복원
./launcher rebuild data # 데이터베이스 컨테이너 리빌드
./launcher rebuild web_only # 웹 앱 리빌드

5단계: 최적화 및 정리

  1. 누락된 pg18 테이블 통계를 생성합니다. 그렇지 않으면 포럼이 평소보다 느려집니다:
docker exec -u postgres data /usr/lib/postgresql/18/bin/vacuumdb -d discourse --analyze-in-stages
  1. 모든 것이 정상적으로 작동하는지 포럼을 테스트합니다 - 유지보수 페이지에 재로드 타이머가 설정되어 있다면 이제 유지보수 페이지가 로드되지 않아야 합니다.
  2. 유지보수 페이지로 향하는 Cloudflare 워커 라우트를 제거합니다(일일 100,000회 제한에 도달하는 것을 원치 않으므로!)
  3. 디스크 공간을 확보하기 위해 이전 pg18 데이터를 삭제합니다:
rm -fr /var/discourse/shared/data/postgres_data_old/

완료! :partying_face: :clinking_beer_mugs:

1번 옵션의 경우, 업그레이드 프로세스가 해당 공간을 사용할 수 있도록 컨테이너에 추가 공간을 마운트해야 하지만, 여전히 용량 확인을 우회해야 하는 것 같습니다.

이것은 마치 닭이 먼저인지 달걀이 먼저인지 같은 문제인 것 같습니다.

스테이징 사이트가 다른 데이터베이스를 사용하고 있다면, 모든 것을 제대로 검증하는 것이 아닙니다. 그 방식을 유지하려면, 백업을 만든 다음 postgres_data를 삭제하고, 빈 데이터베이스로 컨테이너를 다시 빌드한 후 백업을 복원해야 합니다.

하지만 실제로 해야 할 일은 새로운 pg18 서버를 만든 후, 스테이징 서버를 그곳으로 연결하여 정상 작동하는지 확인하고, 그런 다음 프로덕션 서버를 해당 서버로 전환하는 것입니다.

업데이트 중 다음과 같은 오류 메시지를 받았습니다:

Stopping PostgreSQL 15 database server:
main.Stopping PostgreSQL 18 database server:
mainError: The cluster is owned by group id 993 which does not exist ... failed!
failed!

이를 해결하는 방법은 이전 업그레이드의 잔여물을 삭제하고 권한을 수정하는 것이었습니다:

rm -rf /var/discourse/shared/standalone/postgres_data_new
chown -R 999:999 /var/discourse/shared/standalone/postgres_data

… 그런 다음 ./launcher rebuild app을 두 번 실행하고, 선택적으로(마이그레이션이 성공적으로 완료되고 모든 것이 정상 작동하는 경우) ./launcher cleanup을 실행했습니다.

도움이 되길 바랍니다. :slight_smile:

Windows에서 DevContainers를 사용하여 개발 환경을 실행 중인데, 이 오류를 수정할 방법이 있을까요?

추측일 수 있지만, Discourse가 둘을 혼동하고 있는 건가요?

postgres 18이 누락되었거나 secondsite db가 마이그레이션되지 않는 문제를 겪고 있습니다. 이 문제에 대한 도움이 필요하시면 알려주세요.

깨진 멀티사이트 업그레이드에 대한 수정이 대기 중입니다. 준비가 되는 대로 알려드리겠습니다.

멀티사이트 관련 수정 사항을 병합했습니다. 이제 모든 데이터베이스가 정상적으로 업그레이드되어야 합니다. 다음 단계를 수행하여 데이터베이스를 업그레이드 전 상태로 되돌리고 다시 시도할 수 있습니다.

  1. /shared/postgres_data_old 경로에 기존 데이터가 여전히 존재하는지 확인합니다.
  2. /shared/postgres_data 경로에 있는 실패한 업그레이드 데이터를 삭제합니다(여유 있는 디스크 공간이 충분하다면 삭제 대신 이름을 변경해 두는 것도 좋은 방법입니다).
  3. /shared/postgres_data_old를 다시 /shared/postgres_data로 이름을 변경합니다. 또한 Postgres가 해당 디렉터리를 거부하지 않도록 디렉터리 모드가 0700인지 확인해야 합니다.
  4. ./launcher rebuild app 명령을 실행하여 업그레이드를 다시 시작합니다.

그들은 몇 시간 전에 문제를 해결한 것 같습니다.

재구축 메시지에 이 내용을 기록해 두었습니다:

116:C 11 Aug 2026 06:43:27.336 # WARNING Memory overcommit must be enabled! Without it, a background save or replication may fail under low memory condition. Being disabled, it can also cause failures without low memory condition, see vm.max_map_count growing steadily when vm.overcommit_memory is 2 · Issue #1328 · jemalloc/jemalloc · GitHub. To fix this issue add ‘vm.overcommit_memory = 1’ to /etc/sysctl.conf and then reboot or run the command ‘sysctl vm.overcommit_memory=1’ for this to take effect.

이것에 대해 걱정해야 할까요?

53

새 데이터베이스 크기가 이전 크기보다 훨씬 작다는 점도 주목할 만합니다:

root@Forum:/var/discourse/shared/standalone# du -sh postgres_data postures_data_old
6.8G  postgres_data
10G   postgres_data_old
17G	total

이것이 우려스러운가요?

54

이 디렉터리 이름이 좀 이상하지 않나요?

비교를 위해 제 경우를 보면 다음과 같습니다:

:/var/discourse/shared/data# du -sh postgres_data postgres_data_old
4.1G    postgres_data
3.4G    postgres_data_old
55

네, 아마 자동 맞춤법 교정 때문에 그 이름이 깨진 것 같습니다. 실제 이름은 postgres_data입니다.

그러면 새 데이터가 더 컸다는 뜻이네요. 그게 좀 걱정됩니다.

업데이트를 진행했고 모든 것이 아주 잘 진행되었습니다. 첫 번째 재빌드 후 콘솔에 15 버전에서의 업데이트가 성공했다는 메시지와 함께 기존 데이터베이스의 위치 및 재빌드를 한 번 더 실행해야 한다는 안내가 표시되었습니다.

Lilly님의 힌트 덕분에

디스크에 충분한 공간이 있음을 확인할 수 있었습니다.

수정: 추가할 내용

업그레이드 잔여물이 있을 경우를 대비하여 와일드카드를 추가하는 것이 좋겠습니다:

솔직히 이 DB 업그레이드와 공간 요구 사항에 대해 전혀 몰랐습니다. 처음에는 PostgreSQL에서 12GB 부족 오류 메시지가 뜨면서 앱이 재시작되지 않았습니다. 드라이브를 정리해서 약 6GB를 확보하고 다시 실행해 봤지만, 여전히 성공하지 못했습니다.

더 이상 시간을 낭비하지 않고 백업 복원으로 되돌렸습니다.

언제든 @pfaffman처럼 완전히 새로운 서버로 이전해서 PG 18과 최신 Ubuntu LTS를 깨끗하게 설치하는 것부터 시작할 수 있습니다 …

감사합니다. 다음을 확인하기 위해 테스트 마이그레이션을 수행할 예정입니다:

이 주제에 계속 주의를 기울이면서 진행하겠습니다.
