I have tried that. Unfortunately, I have been unable to extract the table name
from the event because TG_TABLE_NAME is not
available during an event trigger, albeit perhaps I am missing something?
You need to use ddl_command_end event and then select from
pg_event_trigger_ddl_commands() . Search for some example how to do this.
That being said, I still believe it is extra work that could easily be avoided
and should be added to the postgresql catalogs simply to be
more feature competitive with Oracle & SQL Server, as well as a boost to the
PostgreSQL community.

Is there any need for a column in pg_class for that? You could just
create an event trigger looking for CREATE TABLE as filter_value:
https://www.postgresql.org/docs/9.6/static/sql-createeventtrigger.html
<https://www.postgresql.org/docs/9.6/static/sql-createeventtrigger.html>
And then have this event trigger just save the timestamp value of
now() in a custom table with the name and/or OID of the relation
involved.
