Likely someone mistakenly added the functions to template1 of the machine you're restoring onto and they're getting added to the new database when it's created.

# psql -U postgres -W template1
Password for user postgres:
psql (8.4.7)
Type "help" for help.

What is your process for creating the database?
Did you run your script once and then run it again after failure? It does not run in a transaction, unless you ask it to, so if it failed on something and you want to run it again, you should drop the database and create it again.
