Quassel IRC

On occasion (in my case, every few days) the postgres database will "forget" the prepared statements given to it by the quasselcore. The immediate effects of this is that attached clients cease to receive any new messages, and newly attached clients will receive zero backlog (all buffers will be empty). Incoming events from IRC also fail to be entered in the database. This will persist until the core is restarted.

Sample log output follows (IRC nicks have been changed to protect the innocent):

Further information:
It has been speculated that the bug occurs when the core loses connection to the database and then reconnects. However, both my core and database run on the same machine, and should be connecting via loopback or local socket.
