* Update a repmgr 3.0 installation to repmgr 3.1
* ----------------------------------------------
*
* 1. Stop any running repmgrd instances
* 2. On the master node, execute the SQL statements listed below,
* taking care to identify the master node and any inactive
* nodes
* 3. Restart repmgrd (being sure to use repmgr 3.1)
* The new repmgr package should be installed first. Then
* carry out these steps:
*
* 1. (If repmgrd is used) stop any running repmgrd instances
* 2. On the master node, execute the SQL statements listed below
* 3. (If repmgrd is used) restart repmgrd

/*
* Set the search path to the name of the schema used by

* If your repmgr installation is not included in your repmgr
* user's search path, please set the search path to the name
* of the repmgr schema to ensure objects are installed in
* the correct location.
*
* The repmgr schema is "repmgr_" + the cluster name defined in
