Hi,
pg_dump and psql are your friends.
Dump the database with pg_dump, take the file and insert it into psql
on the other machine. Details are covered in the manpages of these
programs.
Crude (without options): pg_dump your_db > your_db.dump
psql < your_db.dump
In the manpages you also find the options to dump with all create
statements (e.g. CREATE DATABASE on the new machine) you might need.
pg_dump is also THE solution to make backups. If you simply take the
database files (especially, if the engine is running), you probably
cannot use them either for backup or for transferring due to caching
and other things. With pg_dump you even can transfer your database to
another database engine (from PostgreSQL to Oracle for example), if you
dump it with the option of complete insert statements.
