Macos PostgreSQL的问题

我正在尝试将pg_trgm模块加载到PostgreSQL，但出现了一些问题：

• PostgreSQL 9.0.2（通过自制内置）

无法帮助您使用macos，但在debian linux安装中也经常出现同样的问题。这里有一个非常简单的解决方案：所需的库位于一个单独的包中，名为

postgresql contrib

，该包应该附加在主

postgresql

包中。

重新安装postgresql解决了我的问题。

我知道这是一个老问题，但我是通过谷歌发现的，所以其他人也可能在这里结束

在我的Mac OSX macports安装中，我有两个文件夹，其中包含postgresql的.so文件：

/opt/local/lib/postgresql90/

及

似乎我的安装是在/opt/local/lib/postgresql90/中进行的，而不是在/usr/local/pgsql-9.0/lib/中进行的，因此要安装pg_trgm，我必须执行以下操作：

sudo ln -s /opt/local/lib/postgresql90/pg_trgm.so /usr/local/pgsql-9.0/lib/

---

这应该适用于任何不在正确位置的.so文件。

在生产服务器上，我也这样做了，模块安装成功。在dev机器上，我有contrib文件夹和所需的模块，但它不工作；顺便说一句，在我的OSX 10.7 Lion服务器设置中，要创建的符号链接是：sudo ln-s/opt/local/lib/postgresql90/pg_trgm.so/usr/lib/postgresql/；我通过hotspot找到pg_trm.so，并通过>pg_config--pkglibdir找到.so文件夹（/usr/lib/postgresql）的路径

sudo ln -s /opt/local/lib/postgresql90/pg_trgm.so /usr/local/pgsql-9.0/lib/
