Well, I spent a few hours, today, drafting an implementation for that. You can 
find it at:
 https://github.com/xrg/akonadi/commit/e421f51f0cf501e5e5

(code written against 1.12 for my distro, but could be forward-ported, I 
suppose)

The good news is, that it does reduce the active Postgres connections from 47 
(in my case) down to <10 and even 0 at some points.

Bad news, however, is that it does occasionally segfault. Even though 
DataStore::close() does reset the QueryCache and connection, it seems that 
there is still some lingering Query or pqResult which causes instability. I'm 
investigating...
