how to import csv/data in postgresql - sql

Question

Hy, I know many questions has been asked on it already but this is somewhat different.
I have csv file containing millions of records. I tried the following commands to copy from csv to my table i.e.
copy "client_data" from '/home/mike/Desktop/client_data.txt' with delimiter ',' CSV;
BUT the problem arrises as the data in the csv is inconsistent state i.e.
following lines would like charm
12/12/12 20:17:35,304000000,"123","1"
12/12/12 20:17:36,311000000,"123","2"
12/12/12 20:17:36,814000000,"123","2"
12/12/12 20:17:36,814000000,"123","2"
12/12/12 20:17:37,317000000,"123",".1"
12/12/12 20:17:38,863000000,"123","TS"
12/12/12 20:17:39,835000000,"123","2"
12/12/12 20:17:40,337000000,"123","1"
but hundreds of rows are some what like
12/12/12 20:20:03,790000000,"123","1
{'""}__{""'} /""'\
( $AMZA./)#FRIDI
{__}""'{__} /) (\. ,,DON,,"
12/12/12 20:20:30,501000000,"123","INAM NIKALTA NHE HE KITNE SAWALO K JAWB DAY
/G\A\,':/\,':/S\K,':\"
12/12/12 20:22:55,928000000,"123","PAKISTAN KI BUNYAAD
2=QUAID-E-AZAM"
12/12/12 20:22:56,431000000,"123","QUIED E AZAM
MOHAMMAD ALI JINNAH
[KFK FEROZ]"
which are un parseable due to line breaks, commas, invalid characters, etc.
is there any way to parse these and load the data in postgres table in efficient way?
below is the table structure
create table "client_data" (
date_stamp text,
points bigint,
msisdn character varying(13),
data text
)
with (OIDS = false);
alter table "client_data" owner to postgres;

Did it using MySql import option as MySql had more sophisticated and relative easy import approach for importing data.
