I does that if your distrubtion has packaged postgresql properly and has an 
older major version packaged for pq_upgrade.
Arch Linux for example is where this is the case.

It doesn't do much that akonadi does..

Also Akonadi itself is pretty neutral compared to Evolution which requires a 
whole GNOME session to install.
