Title:
  OpenERP 6.1 stops working after postgresql restart

Status in OpenERP Server:
  New

Bug description:
  That problem is rather critical for us, cause it affects production
  environment. That problem occurs time to time and may lead to serious
  delays in the work, cause OpenERP becomes unusable until somebody
  restarts it.

  We're using OpenERP version 6.1-20121129-003502 on Ubuntu 12 server.
  PostgreSQL 9.1

  Steps to reproduce are the following:
  1) Login to some OpenERP database and logout
  2) Now stop postgresql server (/etc/init.d/postgresql stop)
  3) Try to login to the same database
  4) You got Error message - that is OK
  5) Now start postgresql service (/etc/init.d/postgresql start)
  6) Now try to log into same database again and see error message shown at the end of the ticket description
  Only restart of OpenERP server helps

  
  Expected behavior:
   - OpenERP should automatically clear broken connections from pool and try to reconnect to DB Server

  Additional problems:
  - We're using 2 servers - one for OpenERP and second for PostgreSQL database. So it is not easy for us to write script that will restart OpenERP just after PostgreSQL restart. And obviously that problem need to be solved from OpenERP side.
