Yes, Samurai Jack, I mean Ron --- just kidding. That is my preference too.When you work with several people who are 'Senior' DBA, it's difficult to go to a debate / argument of sort that we should be doing it like this :( Will continue to check things around.Kinda hoping there are some kind of timestamps when a table / index gets created.P.S.:I really wish I can properly learn PostgreSQL hands-on in the real world as a remote intern somewhere.On Sun, Jun 22, 2025 at 9:58 PM Ron Johnson <ronljohnsonjr@xxxxxxxxx> wrote:This is why I do all backups, restores, upgrades, etc through cron.On Sat, Jun 21, 2025 at 8:59 AM Furkan Shaikh <fs626261@xxxxxxxxx> wrote:
No Definitive Proof: Without logs, you cannot get a timestamped log entry saying "pg_restore started/finished." All these methods provide indirect evidence.
Requires Prior Knowledge: Most effective indicators rely on you having some memory or previous records of the database's state (e.g., typical sequence values, expected bloat, average last-vacuum times).
Other Causes: Some of these patterns (like recent statistics) could also be caused by an aggressive VACUUM FULL, a major data import through other means, or an application bug that resets sequences.
Conclusion
The most reliable indicators without direct logs are a sudden and uniform resetting of last_vacuum/last_analyze timestamps to NULL or very recent values across all user tables, combined with a potential change in object OIDs (if you tracked them) or unexpected sequence values. If you see most of your tables

It would be handy if pg_class had created_on timestamp, created_by oid, altered_on timestamp, altered_by oid fields, but alas they don't exist.
