Postgresql 服务器是否在主机上运行；localhost"；？

我对postgresql有意见。我看到一些帖子正在编辑pg_hba.conf，但它不起作用

以下是问题：

sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) could not connect to server: Connection refused (0x0000274D/10061)
        Is the server running on host "localhost" (::1) and accepting
        TCP/IP connections on port 32?
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 32?

和我的pg_hba.conf：

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     trust
# 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.
local   replication     all                                     trust
host    replication     all             127.0.0.1/32            trust
host    replication     all             ::1/128                 trust

如果有人能给我解释一下，我不明白问题出在哪里。

你的博士后考试在进行吗？请尝试使用pgAdmin或某些客户端进行连接。@dassum我使用pgAdmin 4进行了连接，因此我认为它正在运行。编辑pg_hba.conf后是否重新启动或启动了postgres服务器？@wildplasser是的，从Windows上的“服务”重新启动了
