试用支持postgresql wire协议的duckdb服务器duckgres

存储库地址 https://github.com/PostHog/duckgres/

下载二进制文件

wget https://github.com/PostHog/duckgres/releases/download/build-0043e82/duckgres-linux-arm64 -c

在kylin v10中执行报错

复制代码

chmod +x duckgres-linux-arm64
./duckgres-linux-arm64

系统libc等动态库版本太低。

用gcc 14.2 的docker容器来执行。

复制代码

sudo docker start gcc142

sudo docker exec -it gcc142 bash
cd /par
./duckgres-linux-arm64
./duckgres-linux-arm64: /lib/aarch64-linux-gnu/libm.so.6: version `GLIBC_2.38' not found (required by ./duckgres-linux-arm64)

libm动态库版本还是不够高。

再用gcc 15.2的docker容器来执行。

复制代码

sudo docker run -itd -v /home/par:/par --network host --name gcc152 docker.1ms.run/gcc:15.2
afb66b3c7b8e92c47cf2d60a96a34e9fb4ac6147dd0ef054f4f18e7971b4452a
sudo docker exec -it gcc152 bash
cd /par
./duckgres-linux-arm64

可以启动服务端了。但是用DBeaver 的postgresql驱动去连接，报如下错误

复制代码

The server requested password-based authentication, but no password was provided by plugin null

没法登录。

在存储库的"packages"中找到了官方的docker镜像，

拉取镜像, 打上简单的标签

docker pull ghcr.io/posthog/duckgres:f9f5f0a30fd801cae7b4198b3276636e870a6a42

docker tag ghcr.io/posthog/duckgres:f9f5f0a30fd801cae7b4198b3276636e870a6a42 duckgres:dev
运行容器

docker run -itd -v /mnt/c/d:/par --network host --name duckgres duckgres:dev
eb3b126f6fc12942147826398cf087c1853f5b0af0d0afb5729a546ee0601b3c

容器中也没有psql客户端，只有duckdb的插件。

复制代码

docker exec -it duckgres bash
duckgres@DESKTOP-59T6U68:~$ psql
bash: psql: command not found

启动duckgres服务器，发现已经启动了。

利用宿主机上的psql连接，指定localhost，成功了。

复制代码

psql -U postgres -d postgres -h localhost

用duckdb独有的range函数试验，没问题。

再用1亿行generate_series测试，很快。
