Determining the last modified time of a database.

Hi,

There are some unused databases on one of our existing Postgres Dev instance. I am currently in the process of determining those and eventually planning to drop those db’s.

So, how would I determine a database which has not been modified from past few days, lets say a month (or) so? Also is there a way to determine the last time when some one connected to a specific DB and retrieved some information (or) even an idle connection?

Any thoughts on this are highly appreciated. Many thanks in advance.

Thank You,
