Need to move PostreSQL to new hard drive

Hi all -
I just installed a second hard drive on my PC, and set the new drive as the master drive. I need to move all of my PostrgeSQL data from the slave drive to the master drive. I installed PostrgeSQL 8.2.6 on the master drive. Is moving the databases as simple as copy/pasting the PostgreSQL/8.2/data folder from the slave to the master? That almost seems too easy.
