Confluence upgrade 6.13.0 to 6.15.2: Db collation 'C' is not supported

Edited

Updating confluence after email: Confluence Security Advisory - 2019-04-17

Pre-production test.
Upgrade from 6.13.0 --> 6.15.3 (atlassian-confluence-6.15.2-x64.bin)
Debian 8 with PostgreSQL 9.6.10

Upgrade proceeded without error. Upon loading browser for first time:

============================================

Preparing to start Confluence
This page is for Confluence administrators. If you're seeing this page, your Confluence administrator is probably working to restore the service.
We discovered a problem while preparing to start Confluence. If you're a Confluence admin, you can either fix this problem now or ignore it, and start Confluence anyway.
Database: The database collation 'C' is not supported by Confluence. You need to use 'utf-8'.

=============================================

I selected 'ignore it'.
I need to resolve prior to production upgrade. Please advise :-)

Thanks and I choose 'method 2'.
If it should help anyone, the following worked for me. Debian 9, Postgreaql 9.6, Confluence 6.13.

From command line.

1) $ sudo systemctl stop confluence
2) Backup - as owner user ie '<myUser>':
      $ pg_dump confluencedb > dumpfile1
3) Delete original db via psql: DROP DATABASE confluencedb;
4) Make new databse via psql:
      CREATE DATABASE confluencedb WITH OWNER <myUser> ENCODING 'UTF-8' LC_COLLATE 'en_GB.UTF-8' LC_CTYPE 'en_GB.UTF-8' TEMPLATE template0;
      GRANT ALL PRIVILEGES ON DATABASE confluencedb to <myUser>;
5) Restore:
      $psql confluencedb < dumpfile1
6) $ systemctl start confluence

I was then able to update to 6.15.2 without error.

Yes, this work also in my instances, but after that, now I have a lot of 400 Errors like:

In the version before, I did not have this problems, but after changing collation, I have. Any ideas how to fix confluence?

Thanks @Steve Allen this is the sort of simple, accurate information that makes community forums so worthwhile :)
