Re: pg_restore Question

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.

This is why I do all backups, restores, upgrades, etc through cron.

• 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.

Hi,

Without access to the dumpfile or log file, is there any way to check whether a database has been restore either by pg_restore or other means?
