When a PG server is restarted, Orthanc PG connection object is not valid anymore and Orthanc must be restarted in order to create a new PG connection.

In case of 'connection' issue, the PG connection object shall try to reconnect.  That would be helpful to make the connection resilient to other transient errors as well.

This feature has been implemented during the refactoring of the PostgreSQL plugin. The new class `DatabaseManager` is responsible for it: https://hg.orthanc-server.com/orthanc-databases/file/default/Framework/Common/DatabaseManager.cpp
