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 bemore feature competitive with Oracle & SQL Server, as well as a boost to the PostgreSQL community.On Thu, Aug 31, 2017 at 10:54 AM, Michael Paquier <michael.paquier@gmail.com> wrote:On Thu, Aug 31, 2017 at 10:21 PM, Melvin Davidson <melvin6925@gmail.com> wrote:

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
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.
