修改pg_hba.conf文件，一般在安装目录下

# 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
host    all             all             0.0.0.0/0               trust #此行为添加，0.0.0.0/0为所有客户端都可以连接，trust是为了默认postgres用户也可以连接
# IPv6 local connections:
host    all             all             ::1/128                 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local   replication     postgres                                trust
#host    replication     postgres        127.0.0.1/32            trust
#host    replication     postgres        ::1/128                 trust

修改postgresql.conf文件，一般和上一个文件在同级目录下

• 将以下内容

### listen_addresses = 'localhost'

• 修改为

listen_addresses = '*'

重启服务，不知道怎么重启，可以重启电脑
