I am using a user based one. For a PostgreSQL database using as the user and using ~/.local/share/ akonadi/db_data the KDE Userbase wiki has some instructions: https://userbase.kde.org/Akonadi/Postgres_update Also there might be an issue for user based PostgreSQL: Akonadi refuses to start after upgrade to PostgreSQL 12: column "version" of relation "schemaversiontable" already exists https://bugs.kde.org/412629 The Debian bug report libqt5sql5-psql: basic support postgresql-12 https://bugs.debian.org/941763 referenced in the upstream bug report got fixed. But the upstream bug report is still open. So I am not sure whether the issue has been fixed or not. Can anyone provide any clarity on this? Maybe the upstream report has just not been closed yet. Pinging it. So there may or may not be an issues when you go for upgrading Akonadi with a user based, instead of system-wide PostgreSQL setup. Thanks, -- Martin
