Within that database, yes.

I was actually under the impression you had recent experience.
In this case, I would suggest to use the default, eg. let akonadi handle the 
full database.

I run postgresql under a different user and use the backup tools of the 
database to generate backup files.
I prefer not to have a full database inside my home directory.

Yipes!

Seriously, unless you know what you are doing, let akonadi do it itself.
Stop akonadi, wipe the files, and restart akonadi.

Eg. run de database embedded.

You're making things far more complicated than necessary by trying to change 
settings away from the default this much.
