不幸的是，我通过自制软件将 postgis 升级到 2.2.0，现在出现以下错误。我会回到 2.1.0，但该公式似乎不再可用。转到 2.0 会尝试将 Postgres 降级到 9.2。

关于我还能尝试什么的任何想法将不胜感激？

版本：

  • PostGres：9.4.5_2
  • Postgis：2.2.0
  • activerecord_postgis_adapter：3.1.0
  • pg宝石：0.18

以下错误：

PG::UndefinedFile - ERROR:  could not access file "$libdir/postgis-2.1": No such file or directory
:

  activerecord-postgis-adapter (3.1.0) lib/active_record/connection_adapters/postgis/schema_statements.rb:9:in `columns'

基本调试：

$ pg_config --pkglibdir                                        
/usr/local/Cellar/postgresql/9.4.5/lib

$ ls -lrt /usr/local/Cellar/postgresql/9.4.5/lib/postgis
postgis-2.1.so*

/usr/local/Cellar/postgresql/ 仍然显示 9.4.5_1 和 9.4.5_2 的文件夹。我还尝试在 Postgres 上删除、创建和更改 postgis 扩展，并且运行时不会出现问题。当我查找已安装的扩展时：

-[ RECORD 36 ]----+---------------------------------------------------------------------
name              | postgis
default_version   | 2.1.7
installed_version | 2.2.0

在带有自制软件的 OSX 上，我通常会同时更新两者postgresql，postgis如下所示：

brew update
brew uninstall postgis
brew upgrade postgresql
brew install postgis

# update the postgis extension 
psql -d your_database -c "alter extension postgis update"

# recompile the native extensions in the pg gem
gem pristine pg

如果您正在进行主要的 PostgreSQL 更新（例如，从 9.4 到 9.5）并且想要保留您的数据，请首先查看pg_upgrade.

我遇到了同样的问题，ALTER EXTENSION postgis UPDATE;从 postgres shell 运行似乎可以解决问题：

$ \dx  postgis                
| 2.1.7   | public     | PostGIS geometry, geography, and raster spatial types and functions
$ ALTER EXTENSION postgis UPDATE; 
ALTER EXTENSION

$ \dx postgis                
| 2.2.0   | public     | PostGIS geometry, geography, and raster spatial types and functions

之后，错误消失了
