# PostgreSQL 15 with pgvector + pg_bigm extensions
|
||
# 用于 AI 临床研究平台的向量检索和中文关键词检索
|
||
#
|
||
# 扩展版本：
|
||
# - pgvector: 0.8.1 (向量相似度搜索)
|
||
# - pg_bigm: 1.2 (中日韩文本全文搜索)
|
||
#
|
||
# 构建命令：
|
||
# docker build -f Dockerfile.postgres-with-extensions -t ai-clinical-postgres:v1.1 .
|
||
#
|
||
# 使用方法：
|
||
# 1. 构建镜像后，修改 docker-compose.yml:
|
||
# image: ai-clinical-postgres:v1.1
|
||
# 2. 重启服务：docker compose down && docker compose up -d
|
||
# 3. 启用扩展：
|
||
# docker exec -it ai-clinical-postgres psql -U postgres -d ai_clinical_research -c "CREATE EXTENSION IF NOT EXISTS pg_bigm;"
