Postgres location

Postgres location

I have just installed EventLog Analyzer 9 on a new server with the bundled Postgres database. I want to store the data/indexes/archive/logs on another drive on the server. Is there a way to change the location of of these? Our previous setup used MySQL and was setup in this way.
 
We would also like to migrate our old data if possible from the MySQL database to the Postgres database.
 
Thanks
