使用 docker 启动 postgres:15 的时候，报错：
popen failure: Cannot allocate memory initdb: error: The program "postgres" is needed by initdb but was not found in the same directory as "/usr/lib/postgresql/15/bin/initdb"
具体不知道为什么，换成 postgres:15-bullseye 之后就可以使用了。
貌似是因为：
Maintainers of the postgres docker images have updated the underlying OS image layer
