Django 1.8 migration error with postgres

Question

I am new to Django and I am trying to create table in Postgre using Django(1.8)

following is my model class

    class Student(models.Model):
        name = models.CharField(max_length = 50)
        degree = models.CharField(max_length = 50)
        numofsubs = models.IntegerField()
        namesofsubs= models.CharField(max_length = 50)
        details = models.CharField(max_length = 50)

class Meta:

      db_table = "student"

views.py

def addStudent(request):
    student = Student(name = request.name, degree = request.degree ,
     numofsubs = request.numofsubs , nameofsubs = request.nameofparams , details = request.details)
    student.save()
    print 'data saved'

After these changes when I tried to run python manage.py migrate i got django.db.utils.ProgrammingError: permission denied for relation django_migrations

following are the stack traces

Traceback (most recent call last): File "manage.py", line 10, in execute_from_command_line(sys.argv) File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/core/management/init.py", line 338, in execute_from_command_line utility.execute() File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/core/management/init.py", line 330, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/core/management/base.py", line 390, in run_from_argv self.execute(*args, **cmd_options) File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/core/management/base.py", line 441, in execute output = self.handle(*args, **options) File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/core/management/commands/migrate.py", line 93, in handle executor = MigrationExecutor(connection, self.migration_progress_callback) File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/db/migrations/executor.py", line 19, in init self.loader = MigrationLoader(self.connection) File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/db/migrations/loader.py", line 47, in init self.build_graph() File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/db/migrations/loader.py", line 180, in build_graph self.applied_migrations = recorder.applied_migrations() File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/db/migrations/recorder.py", line 60, in applied_migrations return set(tuple(x) for x in self.migration_qs.values_list("app", "name")) File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/db/models/query.py", line 162, in iter self._fetch_all() File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/db/models/query.py", line 965, in _fetch_all self._result_cache = list(self.iterator()) File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/db/models/query.py", line 1220, in iterator for row in compiler.results_iter(): File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/db/models/sql/compiler.py", line 783, in results_iter results = self.execute_sql(MULTI) File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/db/models/sql/compiler.py", line 829, in execute_sql cursor.execute(sql, params) File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/db/backends/utils.py", line 79, in execute return super(CursorDebugWrapper, self).execute(sql, params) File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/db/backends/utils.py", line 64, in execute return self.cursor.execute(sql, params) File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/db/utils.py", line 97, in exit six.reraise(dj_exc_type, dj_exc_value, traceback) File "/usr/lib/ckan/default/local/lib/python2.7/site-packages/django/db/backends/utils.py", line 64, in execute return self.cursor.execute(sql, params) django.db.utils.ProgrammingError: permission denied for relation django_migrations

My settings.py has following conf for db conection

DATABASES = {
    'default': {
       # 'ENGINE': 'django.db.backends.sqlite3',
       # 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'abc',
        'USER': 'xyz',
        'PASSWORD': 'xxxxx',
        'HOST': 'localhost',
        'PORT': 5432,
    }
}
