PostgreSQL 的问题

Question

我正在尝试将 pg_trgm 模块加载到 PostgreSQL，但出了点问题：

无法帮助您使用 macos，但在 debian-linux 安装中经常会出现同样的问题。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，应该另外安装到主postgresql 包中。

Answer 2

我知道这是一个老问题，但我使用 Google 找到了它，所以其他人也可能会在这里结束。

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

/opt/local/lib/postgresql90/

和

/usr/local/pgsql-9.0/lib/

似乎我的安装在 /opt/local/lib/postgresql90/ 中而不是 /usr/local/pgsql-9.0/lib/ 中，所以要安装 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。

重新安装 PostgreSQL 解决了我的问题。
