regression database

Hello,

 

I inherited a production Postgres database server which has a "Regression" database. The problem is that the size of the objects with in the Regression database are increasing so much that the database has grown into several GB.  (Ex: pg_attribute and its index have grown into 2GB each and so on with few other objects as well).

 

I am not sure what the implications of completely deleting the 'Regression' database (I don't need the regression testing). I found the documentation on how to do the regression tests but  can you tell me if there is a documentation of how to take  care of these space issues for "Regression" database?  Or is there a way to reduce the space used by 'Regression' database?

 

I would appreciate your help in resolving this issue.

 

thanks,

Kris.
