After some investigation it seems to me that OBJECT_TSCONFIGURATIONMAP
can't be added for pg_ts_config_map. Because this catalog hasn't Oids.

But this bug can be easily fixed (patch attached). I think in
AlterTSConfiguration() TSConfigRelationId should be used instead of
TSConfigMapRelationId. Secondly, in ProcessUtilitySlow() we can use
commandCollected = true. Because configuration entry is added in
EventTriggerCollectAlterTSConfig() into
currentEventTriggerState->commandList.

This patch only fixes the bug. But I think I also can do a patch which
will give pg_ts_config_map entries with
pg_event_trigger_ddl_commands() if someone wants. It can be done using
new entry in the CollectedCommandType structure maybe.
