I have a development server that is getting crowded.
I would like to see what date the databases have been accessed to determine what ones can be deleted. Is there a way to do this?
The only thing I found when searching was for postgredb:
How to get last access/modification date of a PostgreSQL database?
If you have a table that always gets values inserted you can add a trigger to the update/insert. Inside this trigger you can set the current timestamp in a dedicated database, including the name of the database from which the insert took place.
This way the only requirement of your database is that it supports triggers.
