Hi all,

   I am writing a php script to backup my postgres database through web interface, but my database is password required.  When I do a pg_dump at the linux shell prompt, it will prompt for password in order to backup the database, does anyone know how to pass this password with the pg_dump command together so that I can do it using php system call? 
 I was just reading up on this subject, and it suggests using PGPASSWORD in the environment.  I have not tried that yet, but think all the passwords must be the same. 

It is sometimes unclear to me when challenged for a password, logged in as postgres, whether or not they want the database password I am working on, or postgres'.  So far, it appears to be asking for the postgres password.
