使用自制程序升级到PostGIS 2.1和PostgreSQL 9.3.1时缺少库

Question

在将PostgreSQL从9.2.4升级到9.3.1(通过OS X上的自制程序)的过程中,我遇到了一个奇怪的问题.这是我到目前为止采取的步骤

• 安装了PostgreSQL,PostGIS和必需的库(没有错误)
• initdb在新数据库上运行
• 停止了两台服务器
• 赛跑 pg_upgrade

pg_upgrade 执行必要的检查,创建旧集群的转储,但是当导入新集群时,我收到以下错误:

> ./pg_upgrade -b /usr/local/Cellar/postgresql/9.2.4/bin/ -B /usr/local/Cellar/postgresql/9.3.1/bin -d /usr/local/var/postgres/ -D /usr/local/var/postgres9.3.1 -u postgres

Your installation references loadable libraries that are missing from the
new installation.  You can add these libraries to the new installation,
or remove the functions using them from the old installation.  A list of
problem libraries is in the file:
    loadable_libraries.txt

Failure, exiting

似乎PostgreSQL 9.3.1试图使用不兼容的PostGIS 2.0

Could not load library "$libdir/postgis-2.0"
ERROR:  could not access file "$libdir/postgis-2.0": No such file or directory

Could not load library "$libdir/rtpostgis-2.0"
ERROR:  could not access file "$libdir/rtpostgis-2.0": No such file or directory

有没有人遇到同样的问题？

我最近遇到了这个问题，重新安装 postgis 对我有用。也就是说，转到您压缩源文件的文件夹（如果您从源安装了 postgis）并重新运行：

./configure
make
sudo make install

如果您安装了最新版本的 postgresql，postgis 应该安装到新的 postgresql 的扩展文件夹中：

/usr/share/postgresql/xx/扩展/

要检查，请运行：

sudo su -l postgres

psql template1 -p 5433

SELECT name, default_version,installed_version 
FROM pg_available_extensions WHERE name LIKE 'postgis%' ;

如果 postgis 已成功安装，您应该会看到“已安装”列中指示的版本号。现在，当您尝试运行 pg_upgrade 命令时，一切都应该正常工作。

希望这可以帮助。
