Importing massive amounts of data into a PostgreSQL database

I have a 2.1 million record table to import into a newly-created Postgres
database.  On the machine I have, early calculations predict a 9.5 day
timeframe to do this.  I have dumped the data into a format that Postgres'
COPY command will handle.

Is there any other more efficient way to get massive amounts of data into a
Postgres database?
