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
