修改：

listen_addresses = '0.0.0.0'            # what IP address(es) to listen on;
                                        # comma-separated list of addresses;
                                        # defaults to 'localhost'; use '*' for all
                                        # (change requires restart)
port = 5432                             # (change requires restart)

host    all             all              0.0.0.0/0              password
# 与明文对立的有md5等方式
host    all             all              0.0.0.0/0              md5
# 直接信任某IP，无需验证密码
host    all             all              x.x.x.x/0              trust
