Insert `tsv` files into postgresql db

I have several files which are saved as tsv. I want to insert them into a postgresql db, to analyze them with sql.

However, my problem is how to INSERT this tsv files into postgresql 9.2 under windows 7?

I appreciate your reply!

PS.: I have created the table with the right values like:

CREATE TABLE ratings (distribution VARCHAR, votes VARCHAR, rank FLOAT, title VARCHAR);

the file is in the directory:

C:/Users/testUser/Desktop/TSV/ratings.list.tsv
