Question

由于Heroku的要求，我正在为我的Django项目使用Postgres 9.5 SQL，但是我遇到了无法解决的情况，并希望寻求您的建议。

具体来说，使用Postgres几天后，即使使用正确的密码，系统也无法让我登录（数据库postgres）。当我尝试登录时，我收到以下消息：

'The server doesn't accept connections: the connection library reports

could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "localhost" (::1) and accepting TCP/IP connections on port 5432? could not connect to server: could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connections on port 5432?'

老实说，我没有改变任何事情。我已经在互联网上寻找资源并尝试了以下方法但是徒劳无功：

重置pg_hba.conf以信任所有主机。完成但不工作。以下是我目前的设置：

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# IPv4 local connections:
host     all     all     127.0.0.1/32    trust
# IPv6 local connections:
host     all     all     ::1/128     trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
# host   replication     postgres    127.0.0.1/32    trust
# host   replication     postgres    ::1/128     trust

查找postmaster.pid并将其删除。我搜索了我的驱动器但无法识别该文件。另一方面，我查看了日志文件，似乎没问题。以下是pg_log中的日志文件：

另一方面，我也检查了监听设置，看起来也没问题，如下面postgresql.conf中所示：

listen_addresses = '*'      # what IP address(es) to listen on;

那么，任何人都可以建议如何恢复sql服务？由于此问题，我不想一次又一次地重新安装和重新导入数据库。非常感谢！

即使使用正确的密码
