ducklake-test

启动带有DuckLake（使用PostgreSQL元数据的S3后端存储）的duckgres进行本地测试。在测试duckgres与DuckLake的兼容性或复现Fivetran…时使用。

Start duckgres with DuckLake configuration:

Start dependencies (PostgreSQL metadata store + MinIO object storage):
```
docker-compose up -d
```
Kill any existing duckgres process:
```
pkill -f duckgres || true
```

Ensure config file exists at duckgres_local_test.yaml:

host: "0.0.0.0"
port: 35437
data_dir: "./data"
users:
  postgres: "postgres"
extensions:
  - ducklake
ducklake:
  metadata_store: "postgres:host=localhost port=5433 user=ducklake password=ducklake dbname=ducklake"
  object_store: "s3://ducklake/data/"
  s3_provider: "config"
  s3_endpoint: "localhost:9000"
  s3_access_key: "minioadmin"
  s3_secret_key: "minioadmin"
  s3_region: "us-east-1"
  s3_use_ssl: false
  s3_url_style: "path"

Build and run duckgres:

go build -o duckgres . && ./duckgres --config duckgres_local_test.yaml

Connect with psql (in another terminal):

PGPASSWORD=postgres psql "host=127.0.0.1 port=35437 user=postgres sslmode=require"

To cleanup: pkill -f duckgres && docker-compose down
