service - PostgreSQL 9.2.4 (Windows 7) - 服务无法启动， "could not load pg_hba.conf"

Question

我试图让 Postgres 9.2.4 在 Windows 7 上作为服务运行。安装 postgres 后，该服务运行良好。但是，在将 postgres 设置为另一个程序的服务器后，该服务停止运行。当我现在尝试启动服务时，我收到一条消息:

"The postgresql-x64-9.2 - PostgreSQL Server 9.2 service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs."

当我尝试运行应该使用数据库服务器的程序时，出现此错误:

"A problem was encountered while attempting to log into or create the production database. Details: Could not connect to the server; Could not connect to remote socket. The application must now close"

我在打开同一个程序时也遇到过这个错误:

"A problem was encountered while attempting to log into or create the production database. Details: FATAL: could not load pg_hba.conf The application must now close."

我曾尝试运行以本地系统帐户以及我自己的帐户(在 postgres 服务属性中)登录的服务，但无济于事。我也尝试重新启动我的电脑。经过网上大量的故障排除后，我了解到检查 pg_log 文件是一件好事。以下是最新的 pg_log 条目的内容:

pg_hba.conf 文件似乎有问题，如下所示:

local all all trust
host all all 127.0.0.1 255.255.255.255 trust
host all all 0.0.0.0 0.0.0.0 trust

根据网上的许多建议，我尝试将顶行编辑为许多不同的替代方案(host all all tr​​ust/host all 127.0.0.1/32 trust/host all 192.168.0.100/24 trust 等)。这对我来说很有意义，因为日志文件说 postgres 不支持本地连接并且也指向该行。但是，我的任何更改都没有任何效果。每次更改后我都尝试重新启动计算机，但没有任何区别。

当我搜索 pg_hba.conf 文件通常是什么样子的示例时，这些示例看起来与我的文件略有不同。我注意到在 PostgreSQL 程序文件中，除了 pg_hba.conf 之外，还有一个“20130529-150444-old-pg_hba.conf”文件，它看起来更像我在网上找到的例子。该文件在最后几行之前有几行注释:

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
# IPv6 local connections:
host    all             all             ::1/128                 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
#host    replication     postgres        127.0.0.1/32            md5
#host    replication     postgres        ::1/128                 md5

我希望这是原始的 pg_hba.conf 文件，如果我用旧文件的内容替换新文件，postgres 将再次开始工作。没有这样的运气。我一直希望在 pg_log 中记录更多错误文件，以查看先前陈述的错误是否已消失或更改为其他错误，但没有记录更多文件。

我已经在网上进行故障排除几天了，但我发现没有任何效果。很抱歉问了这么长的问题，但我想彻底了解并包含所有相关信息。如果有人能对这个问题有所了解或提供建议，我将不胜感激。

Windows 计算机不支持本地条目。见 E.20.3.1.3. Authentication .

Reject local lines in pg_hba.conf on platforms that don't support Unix-socket connections (Magnus Hagander)

Formerly, such lines were silently ignored, which could be surprising. This makes the behavior more like other unsupported cases.

更改您的配置:

local  all    all     trust

到:

host   all    all   127.0.0.1/32  trust
host   all    all   ::1/128       trust
