To add to my previous post. If you already have data in a Postgres 
database then you could do:

pg_dump -d db -t some_table -a -f test_data.sql

That will dump the data only for the table in COPY format. Then you 
could apply that to your test database(after TRUNCATE on table, assuming 
you want to start fresh):

psql -d test_db -f test_data.sql
