try using the command: /usr/local/pgsql/bin/pg_dumpall > outputfile ('outputfile' is the name you want for your file) to make a backup of your database. put that copy where your new site will be. then use the new site to restore this file as if it belonged there in the first place by using the command: /usr/local/pgsql/bin/psql -d template1 -f outputfile ('outputfile' is the name you used in step 1) this restores the file you created in the first step to the new installation. that's it. you might have to run initdb, or initlocation on the new installation's data directory.
