Is there a way to get the last record insert/update time in RDBMS. I am specifically looking if PostgreSQL database has a way to provide me this.

I know i can code for this in my every UPDATE/INSERT statement. But if i database can provide me this for every record without me doing any coding that would be great.

Help !!

Unless you implement a strategy to log this, you don't have this information by the database.
Many database systems have some kind of transaction log, but performing an analysis of this takes huge time and often requires some tools...

Ususally, you use some kind of triggers, but I would have to look up how/if this works in PostgrSQL.

i think "last record insert/update time" is not clear enough.

What i mean is - for any record in the database i should be able to find out when was the record last updated.

You have to store this information per row... again, this is not implemented by default, so you need to implement this on your own...

The accepted method is to use a trigger on UPDATE to put an entry in a LOG table. Then a simple SQL statement to find the entry.
