PostGIS310升级334

本文主要是介绍PostGIS310升级334，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

环境：

centos7 + postgis3.1.0alpha1 + postgis3.3.4

如果您运行的是 PostGIS 3 或更高版本，则应升级到已安装的具有PostGIS_Extensions_Upgrade功能的最新版本。

SELECT postgis_extensions_upgrade();

 之前测试过从320升级334，直接执行路径升级即可。

但是从310到334不能平滑升级，看了邮件列表解决方案

邮件列表

数据库postgis库更新到334

注意左边是可安装版本，就是数据库lib/postgis-.so版本，如果不是334，请重新安装postgis

还有办法可以验证是否是最新的postgis，在initdb创建一个库，如果依旧是310dev，说明postgis没有更新成功。

建议先备份下postgis库的so，然后删除掉，再拷贝进去。 

尝试平滑升级

postgres=# ALTER EXTENSION postgis UPDATE TO '3.3.4';
2023-10-11 17:27:37.351 CST [32242] ERROR:  extension "postgis" has no update path from version "3.1.0alpha1" to version "3.3.4"
2023-10-11 17:27:37.351 CST [32242] STATEMENT:  ALTER EXTENSION postgis UPDATE TO '3.3.4';
ERROR:  extension "postgis" has no update path from version "3.1.0alpha1" to version "3.3.4"

extension "postgis" has no update path from version "3.1.0alpha1" to version "3.3.4" 

提示没有更新路径。

a)使用内置扩展升级

postgres=# SELECT postgis_extensions_upgrade();
NOTICE:  Extension postgis_raster is not available or not packagable for some reason
NOTICE:  Extension postgis_sfcgal is not available or not packagable for some reason
NOTICE:  Extension postgis_topology is not available or not packagable for some reason
NOTICE:  Extension postgis_tiger_geocoder is not available or not packagable for some reason

因为我只扩展了postgis，所以提示其他扩展不可打包，那么我们都给他扩展了。

create extension postgis_raster ;
CREATE EXTENSION
create extension postgis_topology ;
CREATE EXTENSION
postgres=# create extension fuzzystrmatch ;
CREATE EXTENSION
postgres=# create extension postgis_tiger_geocoder;
CREATE EXTENSION

b)修改310dev版本号(关键步骤)

因为社区说带阿尔法或者贝塔影响升级。

postgres=# UPDATE pg_catalog.pg_extension SET extversion = '3.1.0' WHERE extname IN('postgis', 'postgis_raster','postgis_sfcgal', 'postgis_topology', 'postgis_tiger_geocoder');
UPDATE 5

c)再次使用upgrade升级

SELECT postgis_extensions_upgrade();

postgres=# SELECT postgis_extensions_upgrade();
NOTICE:  Updating extension postgis from 3.1.0 to 3.3.4
NOTICE:  Updating extension postgis_raster from 3.1.0 to 3.3.4
NOTICE:  Updating extension postgis_sfcgal from 3.1.0 to 3.3.4
NOTICE:  Updating extension postgis_topology from 3.1.0 to 3.3.4
NOTICE:  Updating extension postgis_tiger_geocoder from 3.1.0 to 3.3.4postgis_extensions_upgrade
-------------------------------------------------------------------Upgrade completed, run SELECT postgis_full_version(); for details
(1 row)

d)检查版本 

postgres=# select * from pg_available_extensions;name             | default_version | installed_version |                                                       comment------------------------------+-----------------+-------------------+-------------------------------------------------------------------------------
