It does not necessarily mean that Postgres has to do it. FWIW, you
can track that using an even trigger for CREATE TABLE or other objects
which inserts the following in a table of your choice for a given
database:
- The timestamp of the transaction.
- The object name.
- Its class ID, say pg_class::regclass for a table, etc.
