pg_dumpall: query failed: ERROR: permission denied for relation pg_shadow

[PondRicefied]

When Export (export.php) of phpPgAdmin is run, this errors happen.

-------------------------------------
pg_dumpall: query failed: ERROR: permission denied for relation pg_shadow
pg_dumpall: query was: SELECT usename, usesysid, passwd, usecreatedb, usesuper, valuntil FROM pg_shadow WHERE usesysid <> (SELECT datdba FROM pg_database WHERE datname = 'template0')
-------------------------------------

Why? Please help.

phpPgAdmin's version is 4.0X.
postgresql's version 7.4.X.

the same problem:

Warning: pg_query() [function.pg-query]: Query failed: ERROR: permission denied for relation TABLE-NAME in /home/user/public_html/dima-name.com/test.php on line 7
Query failed: ERROR: permission denied for relation TABLE-NAME

My test cript:

<?php

$dbconn = pg_connect("host=localhost port=5432 dbname=user_db user=user_testik password=xxxxx")
or die('Could not connect: ' . pg_last_error());

$query = 'SELECT * FROM TABLE-NAME';
$result = pg_query($query) or die('Query failed: ' . pg_last_error());
echo $result;
?>

any ideas?

The problem is user doesn't have any privileges to access tables.
If I am adding privileges for database through PHPPgAdmin all is working fine.
So, why when I adding user to database via cpanel it doesn't give me option to choose privileges?

P.S. Sorry for my English
