How to import a CSV file (originally from Excel) into a Postgresql 8.0.7 database

Hello,

I am trying to import an Excel file in my database (8.0.7). I think I am
supposed to create an CSV file out of my Excel file and somehow, feed the
database with it. My pronblem is that I don't really know how to do it... :(
Can anyone give me a hint about how to do that?
One last "detail", the Excel files contains roughly 45.000 lines and 15
columns. So, I need a fast and efficient method.

Here is my database:

--
-- PostgreSQL database dump
--

SET client_encoding = 'UNICODE';
SET check_function_bodies = false;
SET client_min_messages = warning;

SET search_path = public, pg_catalog;

--
-- Data for Name: Flight Traffic; Type: TABLE DATA; Schema: public; Owner: ted
--

COPY "Flight Traffic" ("AR", "ICAOAIRP", "MOTORTYP", "VIKT", "ICAOTYP",
"FROMTO", "ANTAL", "CLASS", "SUBCLASS", "BULLERKLASS", "MILJOKLASS",
"ANTAL_PAX", "ARRDEP", "INTDOM", "KUNDNAMN") FROM stdin;
2004 ESDF - 0 RALL ESME 1 P F 3
0 0 A D FORSBERG
\.

--
-- PostgreSQL database dump complete
--

And here is the .CSV i try to import:

2004,"ESDF","-",0,"RALL","ESME",1,"P","F",3,0,0,"A","D","FORSBERG, N MARTIN"
