Data Versioning

Does any body know if pgsql supports any kind of versioning of  binary objects or data. e.g. If I'm storing a binary file in a row of a table, I would want to see different versions of the same biary file. Everytime I do a write, the version number should be bumped up !!

 

Is it possible to do it in pgsql or any other databases.

I'm using JDBC for connecting to database.

 

thanks
