Postgresql 用户问题

Question

在整个崩溃过程中，我已经多次通过 brew 卸载并重新安装了 postgresql。

我正在尝试过渡到使用 postgresql.app... 但是每当我尝试启动程序时，我都会收到一条错误消息，并告诉我检查日志。

LOG:  could not bind IPv6 socket: Address already in use
HINT:  Is another postmaster already running on port 5432? If not, wait a few seconds and retry.
LOG:  could not bind IPv4 socket: Address already in use
HINT:  Is another postmaster already running on port 5432? If not, wait a few seconds and retry.

此时我不知道该怎么办...我正在尝试删除与 postgresql 相似的任何内容。任何建议将不胜感激。

您可以尝试查找当前正在监听localhost:5432的进程

sudo netstat -tpln | grep 5432

您将获得 PID。根据它是什么，您可能需要杀死它并重新启动 Postgres 或识别在 5432 上运行的程序以停止它自动运行或将其删除。
