Does pg_dump still work??? That is probably the best method to move PostgreSQL databases around.
Export:
pg_dump NameOfDatabase > DumpofDatabase.NameOfDatabase.pgsql
Import
pgsql NameOfDatabase < DumpofDatabase.NameOfDatabase.pgsql
and if you need to clear out an old database before importing a newer version:
dropdb NameOfDatabase.

A couple of safety tips worth mentioning on the above procedure:
1. Make sure the directory/files on the new server are still owned by
the database user -- usually postgres.
2. This will only work if the hardware architecture (i.e. i686 versus
x86_64) and database version (e.g. 7.4.x) is the same on the two
machines.
