Re: pg_upgrade issue, upgrading from v10 to v14

[Daulat <daulat.dba@xxxxxxxxx>]

Hi David,

During upgrade, we are still getting the same error message. 

I have followed the following steps on Postgres14.

- Installed postgis version.  sudo apt install postgresql-14-postgis-2.5

and then connected to pg 14 and checked the extension. 

postgres@zuber-Lenovo-C40-30:~$ psql -U postgres -p 5436
psql (14.4 (Ubuntu 14.4-1.pgdg18.04+1))
Type "help" for help.

postgres=#  \dx
                                List of installed extensions
  Name   | Version |   Schema   |                        Description                        
---------+---------+------------+------------------------------------------------------------
 plpgsql | 1.0     | pg_catalog | PL/pgSQL procedural language
 postgis | 3.2.1   | public     | PostGIS geometry and geography spatial types and functions

(2 rows)

If i create a new database and tried to create extension postgis

postgres@zuber-Lenovo-C40-30:~$ psql -U postgres -p 5436
psql (14.4 (Ubuntu 14.4-1.pgdg18.04+1))

Hi Team,

Please help on the postgres upgrade issue. We are upgrading from v10 to v14

IOW, you are using PostGIS, read their documentation and inspect their version matrix and decide on an upgrade path you want to follow, ensuring that when you run pg_upgrade the same version of PostGIS exists in the old and new clusters.

Or take the first option and uninstall PostGIS on the existing server.
