I know of three ways to do this:
1. Log out and log back in as postgres. 
2. Set up sshd and then execute "ssh postgres@localhost". 
3. Use Fast User Switching to switch user to postgres.  
 Obviously cannot be scripted
 Can be scripted but assumes that sshd is set up.
 Only available on XP and later.

installation (unless one assumes sshd is set up). This is why the
PostgreSQL does not contain an installation script like some of the
