How to import PostgreSQL 9.2.4 dump to PostgreSQL 9.4.5?

Hi guys,

I'm running some test.

However, I'm stuck in restoring a PostgreSQL 9.2.4 dump to PostgreSQL
9.4.5 database.
I'm doing the backup using pg_dump version PostgreSQL 9.2.4 in text
file (SQL dump).
I'm trying to restore it to PostgreSQL 9.4.5 usng psql.

The restoration error message was as below:
psql:room.sql:41695: invalid command \n
Query buffer reset (cleared).
psql:room.sql:41696: invalid command \n
Query buffer reset (cleared).

The SQL statement in the file as below:
COPY room (id, user_id, partner_id, rm_cr_ts, rm_up_ts, rm_sv_ts,
value, last_dlvrd_to_user, last_dlvrd_to_prtnr, last_seen_by_user,
last_seen_by_prtnr, num_unseen_by_user, num_unseen_by_prtnr,
last_message_id, last_message_ts, legacy_id, legacy_last_message_id,
inserted_at, updated_at) FROM stdin;

I create the room table as below:
CREATE TABLE room (
id integer NOT NULL,
user_id character varying(255),
partner_id character varying(255),
rm_cr_ts bigint,
rm_up_ts bigint,
rm_sv_ts bigint,
value character varying(255),
last_dlvrd_to_user bigint,
last_dlvrd_to_prtnr bigint,
last_seen_by_user bigint,
last_seen_by_prtnr bigint,
num_unseen_by_user integer,
num_unseen_by_prtnr integer,
last_message_id integer,
last_message_ts bigint,
legacy_id text,
legacy_last_message_id text,
inserted_at timestamp without time zone NOT NULL,
updated_at timestamp without time zone NOT NULL
);

All the servers are Debian 7.8 (Wheezy) with hardware:
- CPU 24 cores
- RAM 128GB
- SSD 128GB

Have anyone try this before?
How to do it properly?

Thanks in advance,
Fattah
