PostgreSQL: pg_dump fails with permission denied

Question

Today I have tried to dump my PgSQL database, something I do from time to time without any trouble, but it failed:

borelupo@l5nets02:~$ pg_dump -f spam-20150123.sql -F p -O -C -h x.x.x.x -U borelupo spam
Password:
pg_dump: SQL command failed
pg_dump: Error message from server: ERROR:  permission denied for relation badports
pg_dump: The command was: LOCK TABLE public.badports IN ACCESS SHARE MODE

Now, the user borelupo is owner of the table, how can he get permission denied at all?

spam=> \d
         List of relations
Schema |     Name      | Type  |  Owner
-------+---------------+-------+----------
public | badports      | table | borelupo

What gives? PostgreSQL is 9.1.14.

Edit: When I connect as admin user (postgres), the dumps works OK. But I'd surely like not needing to login into db server, switch users etc.

Answer 1

I think I've found the problem: Being owner of said table doesn't mean having all privileges. So I really lacked the privileges for given table. My bad.

Answer 2

The issue for me was that my postgres role was not a SUPERUSER; this was fixed via ALTER ROLE postgres SUPERUSER;.
