 The connection to the server was lost. Attempting reset: WARNING:

 DETAIL:  The postmaster has commanded this server process to roll back the
 current transaction and exit, because another server process exited
 abnormally and possibly corrupted shared memory.
 HINT:  In a moment you should be able to reconnect to the database and
 repeat your command.
