中级别 1人工审核postgres

说明

By default, listen_addresses is set to localhost which prevents any and all remote TCP connections to the PostgreSQL port. Some Docker images may set listen_addesses to *. * corresponds to all available IP interfaces; thus, the PostgreSQL server then accepts TCP connections on all the server's IPv6 and IPv4 interfaces.
