我想在本地试用 Discourse，于是使用了 Docker Compose 尝试搭建： version: '3.8' services: postgres: image: pgvector/pgvector:pg17 container_name: discourse-postgres restart: always environment: POSTGRES_USER: discourse POSTGRES_PASSWORD: discourse POSTGRES_DB: discourse # 确保扩展能正常加载 # POSTGRES_INITDB_ARGS: "--enable-extensions=vector" volumes: - ./data/postgres:/var/lib/postgresql/data healthcheck: test: ["CMD-SHELL", "pg_isready -U discourse && psql -U discourse -c 'SELECT * FROM pg_extension WHERE extname = ''vector'';'"] interval: 10s timeout: 5s retries: 5 redis: image: redis:7-alpine container_name: discourse-redis restart: always volumes: - ./data/redis:/data healthcheck: test: ["CMD", "redis-cli", "ping"] interval: 10s timeout: 5s retries: 5 discourse: image: discourse/discourse:stable container_name: discourse-app restart: always depends_on: postgres: condition: service_healthy redis: condition: service_healthy ports: - "80:80" environment: DISCOURSE_DB_HOST: postgres DISCOURSE_DB_USER: discourse DISCOURSE_DB_PASSWORD: discourse DISCOURSE_REDIS_HOST: redis DISCOURSE_DEVELOPER_EMAILS: "admin@example.com" DISCOURSE_HOSTNAME: "localhost" # 临时SMTP配置（启动后需修改为真实值） DISCOURSE_SMTP_ADDRESS: "smtp.example.com" DISCOURSE_SMTP_PORT: 587 DISCOURSE_SMTP_USER_NAME: "admin@example.com" DISCOURSE_SMTP_PASSWORD: "password" # 可选：禁用不必要的AI功能，减少扩展依赖（如需） DISCOURSE_DISABLE_VECTOR_SEARCH: "true" volumes: - ./data/discourse:/var/www/discourse/shared 但是遇到了阻碍我体验 Discourse 论坛的问题： discourse-postgres | 2026-01-20 09:19:47.774 UTC [140] ERROR: column "vector" does not exist at character 44 discourse-postgres | 2026-01-20 09:19:47.774 UTC [140] STATEMENT: SELECT * FROM pg_extension WHERE extname = vector; 不知道是什么原因，有老手能指导吗？

You need the pgvector extension for postgres. Also, discourse won’t work without https. If you really want a local install, you should use development install.

This is not a #bug. This is not the supported local install. See #dev-install
