Title:
  datetime used for string column query crashed postgresql driver

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  branch: master
  testing commit: cd4093e0f2a7d07fa81915dc4866f4ac7324a028

  The sql database is postgresql 9.1. The driver is psycopg2.

  You can  easily reproduce it by enabling instance_usage_audit in
  nova.conf and run nova-compute.

  
  This bug should influence released version too if it is there for a long time.
