我在 MAC 上遇到 CitusData docker 版本的问题。

SQLSTATE[08006] [7] could not connect to server: Connection refused 

docker 容器列表如下：

Answer 1

5433 端口似乎是主容器中的问题。0.0.0.0:5433->5432/tcp. PostgreSQL 默认使用 5432 端口，这似乎是连接被拒绝的原因。

您是否更改了默认端口映射docker-compose.yml？也许您MASTER_EXTERNAL_PORT=5433在尝试访问 citus 数据库时设置并忘记使用它。

如果您想继续使用5433端口，您可以使用psql -U postgres -h localhost -p 5433连接到数据库。
