Our application executes come scripts with the code consist of DDL which creates lot of objects in the database in various schemas,also there are lot of connections firing the same code. I am able to locate the IP from where the script is initiated (which is causing more load on the database ), but I would like to know if I can pinpoint the relations which are created on a specific date and time or else I can do something through which I get creation date and time of the objects.you would need to have postgres configured to log DDL, and set the log prefix to include timestamping, then you could scan those logs to get that information. its not otherwise stored in the database.
Logging is the best way of capturing these events.
You can probably find out the relfilenode from pg_class for a given relation name (relname) and then go to the datadirectory (or tablespace directory) --> db directory (mapped to oid of pg_database) --> filename. Check the date time of the file when it was created.
Though I don't think this infra has been built for this very purpose.
