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.
Is this creation timestamp info exposed in Linux (ext4,xfs,etc?)? Last time I
checked this info was available in FreeBSD out of the box.
Though I don't think this infra has been built for this very purpose.
