Sounds like a problem with your file. Messing up CR/LF characters when
moving things between Windows and UNIX systems is a popular one. Proof
it works:
$ psql -c "create table t(i integer)"
CREATE TABLE
$ cat test.sql
INSERT INTO t(i) VALUES (1);
INSERT INTO t(i) VALUES (2);
INSERT INTO t(i) VALUES (3);
INSERT INTO t(i) VALUES (4);
$ psql < test.sql
INSERT 0 1
INSERT 0 1
INSERT 0 1
INSERT 0 1
You might also try this:
psql -ef filename.sql
Which will show you the command that's being executed interleaved with
the output; that can be helpful for spotting what's wrong with your
input file.
P.S. The fast way to get lots of data into PostgreSQL is to use COPY,
not a series of INSERT statements. You may want to turn off
synchronous_commit to get good performance when doing lots of INSERTs.
