Обсуждение: BUG #15038: Upgrade 8.4 to 9.2 - LC_Collate differs

The following bug has been logged on the website:

Bug reference:      15038
Logged by:          Dominic

PostgreSQL version: Unsupported/Unknown
Operating system:   Windows Server 2016
Description:

Hi folks,

I need to upgrade an old Atlassian Confluence system which is using a
postgreSQL DB (8.4.22). 
Since the newer version doesn't support v8.4.22 anymore, I need to upgrade
the database to 9.2.

I setup a test environment with the same DB version and got it running. If I
try to upgrade using pg_upgrade I experience an error, pointing towards
different lc_collate values.

In 8.4 it's "German, Germany" while in 9.2 the value says
"German_Germany.1252".
The bug is also described in BUG #14734.

I couldn't find any fixes for this.

I cannot create a 8.4 DB with "German_Germany.1252" and neither a 9.2 DB
with "German, Germany". 

Anyone got a clue how to fix this?

Cheers!

Hi Dominic,

Support for PostgreSQL v9.2 ended in September 2017:

https://www.postgresql.org/support/versioning/

Also, it's listed with a warning icon on the Confluence Supported Platforms documentation, so they don't recommend it
either:
 

https://confluence.atlassian.com/doc/supported-platforms-207488198.html

I would strongly recommend that you upgrade to PostgreSQL v9.6, which is the latest version supported by both the
PostgreSQLcommunity and Confluence.
