18.12. Registering Event Log on Windows
To register a Windows event log library with the operating system, issue this command:
regsvr32 pgsql_library_directory/pgevent.dll
 
  This creates registry entries used by the event viewer, under the default
   event source named
  
   PostgreSQL
  
  .
 
  To specify a different event source name (see
  
   event_source
  
  ), use the
  
   /n
  
  and
  
   /i
  
  options:
 
regsvr32 /n /i:event_source_name pgsql_library_directory/pgevent.dll
 
To unregister the event log library from the operating system, issue this command:
regsvr32 /u [/i:event_source_name] pgsql_library_directory/pgevent.dll
 
Note
   To enable event logging in the database server, modify
   
    log_destination
   
   to include
   
    eventlog
   
   in
   
    postgresql.conf
   
   .
