QGIS doesn't handle PostGis connection resets?

I'm highly frustrated by the fact that if I leave the database alone for a more than a few minutes, I can no longer insert new lines. If I restart QGIS, everything goes back to normal. I believe this is caused by the tcp connection being closed (same problem that causes crashes in PgAdmin)?

Any way to mend that from QGIS side? Or do I have to increase timeouts somehow?

Will pgbouncer help here?
