If you are using pg 7.3, store the password in the .pgpass file in
the home directory of the user instead. It's safer. Keep in mind
that the environment variable might be exposed to others logged into
the machine. (If no-one else logs into the machine, why not use
trust for local users?)

But if you must use it, you can just set it at the beginning of the
script:

PGPASSWORD=[yourpasswordhere]
/path/to/pg_dumpall
