Hi Christian,
I followed some weird howtos in the WildWildWild-Internet and did a wrong setup.
[1] has the correct instructions.
The issue was when the akonadi-database ran as an own
postgresql-instance/process when looking with `ps -ef | grep s[q]l`.
So, I saw two processes - one owned by "postgres" the other
(akonadi-database) by my user "dileks".
By following the new instructions this is no more the case - I have
one process owned by "postgres".
* The issues with AppArmor are no more visible in dmesg-logs! *
It's true "akonadi-server" Debian package ships an own aa-profile:
root# dpkg -L akonadi-server | grep apparmor
/etc/apparmor.d
/etc/apparmor.d/mysqld_akonadi
/etc/apparmor.d/postgresql_akonadi <--- XXX: Look here
/etc/apparmor.d/usr.bin.akonadiserver
Christian, you mean to add the change like below?
[ /etc/apparmor.d/postgresql_akonadi ]
#include <tunables/global>
@{xdg_data_home}=@{HOME}/.local/share

}

So, if this is a change you favour, please let me and the Debian-KDE team know.
See below my "howto-switch-akonadi-database-from-mysql-to-postgresql.txt"
for full instructions and get rid of MySQL/MariaDB entirely.
If you need further information, please let me know.
Thanks.
