Permissions pg_dump / import

Hi guys,

I'm running a pg_dump and then importing the dump into a test server. I'm
using PostgreSQL 9.5.

*pg_dump:*

> pg_dump --dbname=prod1 --host= servername --port=5432 --username=user1 -v
> -f test1_NEW.sql

*Steps into the new database (test1):*

> CREATE SCHEMA public;
> GRANT ALL ON SCHEMA public TO user1;
> psql -h servername -U master --port=5432 --dbname=test1 -f test1_NEW.sql

I get lots of errors like:

psql:test1_NEW.sql:212: ERROR: must be owner of relation accounts_id_seq

prod1=> \d+ accounts_id_seq
> Sequence "public.accounts_id_seq"
> Column | Type | Value | Storage
> ---------------+---------+---------------------+---------
> sequence_name | name | accounts_id_seq | plain
> last_value | bigint | 33 | plain
> start_value | bigint | 1 | plain
> increment_by | bigint | 1 | plain
> max_value | bigint | 9223372036854775807 | plain
> min_value | bigint | 1 | plain
> cache_value | bigint | 1 | plain
> log_cnt | bigint | 32 | plain
> is_cycled | boolean | f | plain
> is_called | boolean | t | plain
> Owned by: public.accounts.id

What do I have to do? Should I revoke the permissions on the prod1 database
before performing the dump?

Cheers;
Patrick
