pgdump (9.2.4) not dumping all tables

hello im trying to dump a complete DB, i've been doing something like this.
(i'm in the process of upgrading from 9.2.4 to 9.3.5)

my current DB looks like this:
Name | Owner | Encoding | Collate | Ctype | Access privileges
-----------+----------+-----------+-------------+-------+-----------------------
DB | postgres | UTF8 | en_US.UTF-8 | C | =Tc/postgres +
| | | | |
postgres=CTc/postgres+
| | | | |
jp=CTc/postgres

having 171 tables

my dump has been done with this:

0) su postgres -c "/usr/local/pgsql9.2.4/bin/pg_dump -p 5433 -Fc -v $db >
$backup_path/$db.bkp"

1) then i create the DB (i postgis enable it)
2) and then do the restore with a postgis perl script
su postgres -c "export
PATH=/usr/local/pgsql9.3.5/bin/:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
&& perl /dls/gis/postgis-2.1.3/utils/postgis_restore.pl $baclup_file |
/usr/local/pgsql9.3.5/bin/psql -h localhost -p 5432 -U postgres $db 2>
$backup_path/$db_upgrade_errors.txt"

everything seems to work fine until i noticed that i'm missing 5 tables,
doing a diff on two files i find out which 5 tables are missing, there is
nothing special about this tables except that I noticed some empty fields ,
like this:

id | x | y | name | placetype |
point_geom
------+---+---+-------------------+-----------+----------------------------------------------------
1 | | | Km. 223123 RN-09 | 1 |
0101000020E6100000F75BB76C0C1A57DCasdaas2F40
2 | | | Km. 223120 RN-09 | 1 |
0101000020E6100000ECFCasdasdasd1D3FC122F40

then i try to do an individual dump of the missing tables (which is not so
tedious giving the fact that it are only 5 tables)

but when i see the dump file those empty fields are translated to something
like this :

COPY al_shared_place (id, x, y, name, placetype, point_geom) FROM stdin;
1 *\N \N * Km. 223123 RN-09 1
0101000020E6100000F75BB76C0C1A57DCasdaas2F40
2 *\N \N * Km. 223120 RN-09 1
0101000020E6100000ECFCasdasdasd1D3FC122F40

so when i do the restore of the table

SET
SET
SET
SET
SET
SET
ERROR: relation "al_shared_place" does not exist
invalid command \N
invalid command \N
invalid command \N
invalid command \N
invalid command \N
invalid command \N

thanks for your help.

NOTE: is important to mention that my DB is a postgis enable DB, i don't
think this is the issue that's why im asking here because i think its more
an encoding missmatch or something like that.
