Hi, We have configured PostgreSQL cluster with repmgr 3.0.1 and PgPool2 3.2 on Ubuntu 14.04. Now we are getting the following error messages in the log file. ERROR: duplicate key value violates unique constraint "pk_os_currentstep" ERROR: cached plan must not change result type Any suggestion will be appreciated.
