You really need to get up close and personal with the fine manual.

See:
-----------
http://developer.postgresql.org/pgdocs/postgres/sql-copy.html

Specifically:
-----------
Synopsis

COPY table_name [ ( column [, ...] ) ]
FROM { 'filename' | STDIN }
[ [ WITH ] ( option [, ...] ) ]

Example:
-----------
regression=# create table foo(f1 serial, f2 text);
NOTICE: CREATE TABLE will create implicit sequence "foo_f1_seq" for
serial column "foo.f1"
CREATE TABLE
regression=# copy foo (f2) from stdin;
Enter data to be copied followed by a newline.
End with a backslash and a period on a line by itself.
>> hello
>> world
>> \.

regression=# select * from foo;
f1 | f2
----+-------
1 | hello
2 | world
(2 rows)
