Question

不幸的是，我通过自制软件升级到postgis到2.2.0，我现在得到以下错误。我会回到2.1.0，但公式似乎不再可用了。 2.0试图将Postgres降级到9.2。

对于我还能尝试的其他任何想法都会非常感激吗？

版本：

PostGres：9.4.5_2
Postgis：2.2.0
activerecord_postgis_adapter：3.1.0
pg gem：0.18

以下错误：

PG::UndefinedFile - ERROR:  could not access file "$libdir/postgis-2.1": No such file or directory
:
  activerecord (4.2.4) lib/active_record/connection_adapters/postgresql_adapter.rb:596:in `block in exec_no_cache'

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 /仍显示9.4.5_1和9.4.5_2的文件夹。我也试过在Postgres上删除，创建和修改postgis扩展，并且运行没有打嗝。当我查找已安装的扩展程序时：

-[ RECORD 36 ]----+---------------------------------------------------------------------
name              | postgis
default_version   | 2.1.7
installed_version | 2.2.0
comment           | PostGIS geometry, geography, and raster spatial types and functions

Answer 1

我有同样的问题，从postgres shell运行ALTER EXTENSION postgis UPDATE;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

Answer 2

在使用自制软件的OSX上，我通常会同时更新postgresql和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）并希望保留您的数据，请先查看pg_upgrade。

Postgis 2.2.0和Postgres 9.4.5的问题：PG :: UndefinedFile - 错误：无法访问文件“$ libdir / postgis-2.1”
