Due to a bug in the EventSentry configuration assistant, the EventSentry database (PostgreSQL only) may create duplicate constraints when updating a PostgreSQL database. These constraints can be removed by downloading and running a SQL script (see "Additional Links" below) from within pgAdmin:
Running this script is optional and only necessary once. As soon as you have upgraded to EventSentry v3.2.1.6 or higher, running the configuration assistant will no longer create duplicate constraints.
