To connect to a different database just edit the JDBC connection string in the existing <confluence_home>/confluence.cfg.xml. Look for something like:

 <property name="hibernate.connection.url">jdbc:postgresql://<hostname>:<port#>/<db_name></property>

If you don't find the connection URL there, try the <confluence_install>/conf/server.xml file:

 url="jdbc:postgresql://<host>:5432/<database-name>"
