無論如何都無法獲得關係的權限

Question

我已經嘗試過幾乎所有可以獲得postgres中某些關係的用戶權限。以下是我已經試過：

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO myuser; 
GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public TO myuser; 
ALTER DEFAULT PRIVILEGES GRANT ALL ON TABLES TO myuser; 
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT ALL ON TABLES TO myuser; 

我已經改變了我pg_hba.cnf這樣：

# TYPE DATABASE  USER   ADDRESS     METHOD 

# "local" is for Unix domain socket connections only 
local all    all          trust 
# IPv4 local connections: 
host all    all    127.0.0.1/32   trust 
# IPv6 local connections: 
host all    all    ::1/128     trust 
# Allow replication connections from localhost, by a user with the 
# replication privilege. 
#local replication  postgres        peer 
#host replication  postgres  127.0.0.1/32   ident 
#host replication  postgres  ::1/128     ident 

我敢肯定，如果你擺弄他們的權利，這些命令做一些事情，但爲什麼這些命令中沒有任何一個能夠在接近他們所說的地方做任何事情？

我使用python：

>>> conn = psycopg2.connect(host="localhost", port="5432", dbname="mydb",user="myuser", password="mypassword") 
>>> cur = conn.cursor() 
>>> cur.execute('select count(*) from mytable') 

這是我得到的錯誤：

>>> cur.execute('select count(*) from public.mytable') 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
psycopg2.ProgrammingError: permission denied for relation mytable 

我也試過：

ALTER DATABASE mydb OWNER TO myuser; 

並反覆重啓，當然。

Answer 1

您是否在mydb分配了所有者myuser？ 這是解決你的問題一個簡單的方法：

CREATE DATABASE mydb OWNER myuser;

Answer 2

所以每this的答案，我可以通過單獨給予它一個表，我想以訪問我必須做的每個表。

仍然不知道爲什麼這工作。

GRANT ALL PRIVILEGES ON TABLE mytable TO myuser; 

而這些都沒有。

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO myuser; 
GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public TO myuser; 
ALTER DEFAULT PRIVILEGES GRANT ALL ON TABLES TO myuser; 
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT ALL ON TABLES TO myuser;
