[ADMIN] How to configure Postgre 8.2 to put the data base in a especific directory

[David Rodríguez Canelón]

I put the tablespace in a specific directory, but Postgre created a copy of my 
database in de Postgre directory (C:\Archivos de 
programa\PostgreSQL\8.2\data\base\10818), taking all my free space. I need to 
know how i could set Postgre to create a database in a  diferent directory and 
drive than Postgre's.
