The General mail list archive does cover this, but for novices like me a more explicit set of directions might be helpful. Here's my attempt to contribute, but I make no guarantees. Basically, as I understand it, you need to create a new database with the name you want and then load it with your old data. In BASH: 1: create the database you want your old one (which we'll call OldName) to be called. We'll call it NewName: type: CREATEDB NewName 2: create an SQL file that contains your data and most of your metadata: type: pg_dump OldName > OldName.sql 3: you can now edit the SQL that you will use to create your new database with a text editor, if you want, but the 'renaming' actually occurs when you load the database into NewName. type: psql -e NewName < OldName.sql 4: destroy your old db if you want -- and after you make sure all this worked! type: DESTROYDB OldName Comments: 1: If you don't need to edit the SQL file, you can combine steps 2 and 3. type: pg_dump OldName | psql NewName -e 2: Be aware of the limitations of pg_dump, notably that it does not cover views and some other stuff you've created. You may want to consider creating your views by building your SQL in a file and then running the SQL on your database. That makes editing your views and reloading them in the future quite a lot easier. 3: Before you do this and risk your data, check out each of these commands at http://www.postgresql.org/docs/man/ :-) DTB
