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.
