[BUG?] pg_event_trigger_ddl_commands() error with ALTER TEXT SEARCH CONFIGURATION

Hello hackers,

I attached the test extension. It just creates event trigger on
ddl_command_end. And pg_catalog.pg_event_trigger_ddl_commands() is
executed from extension's C-function handler.

The pg_event_trigger_ddl_commands() returns the error:

ERROR:  unrecognized object class: 3603

if I try to execute the following commands:

=> create text search CONFIGURATION en (copy=english);

=> alter text search CONFIGURATION en ALTER MAPPING for host, email,
url, sfloat with simple;
ERROR:  unrecognized object class: 3603
CONTEXT:  SQL statement "SELECT objid, UPPER(object_type), object_identity,
   UPPER(command_tag)
   FROM pg_catalog.pg_event_trigger_ddl_commands()"

This error is raised from getObjectClass() function. It seems that we
need new OCLASS_TSCONFIG_MAP object class.

Is this a bug? Or it wasn't added intentionally?

Thanks in advance.
