When I start Confluence-7.2.0, and visit its' page, the server reports;
Database: The database collation 'C' is not supported by Confluence. We recommend utf-8. On Windows you can also use the Windows-1252 collation for your locale.
But when I enter my psql server to review my database the below is reported;
| Encoding | Collate | Ctype |
| UTF8 | en_GB.UTF-8 | en_GB.UTF-8 |
This issue was initiated when an upgrade was cancelled, which understandably left the data out-of-sync.
