database - PostgreSQL 9.6数据库上的关联权限被拒绝

Question

我在创建的数据库中创建新对象(特别是 View )时遇到问题。尽管SO上报告了许多类似的问题，请参见permission denied for relation和permission denied for sequence，但是尽管研究了可接受的答案(在某些情况下，遵循PostgreSQL文档)，但我仍无法解决此问题。

这是我正在运行的用于创建数据库，新角色然后更改数据库默认权限的脚本的片段:

-- # Uncomment line below for debugging purposes
SET client_min_messages TO debug1;

CREATE DATABASE mydatabase WITH ENCODING 'UTF8' TEMPLATE template1;

-- Create user foo
CREATE ROLE foo LOGIN ENCRYPTED PASSWORD '29829932499gd' NOINHERIT;


\c mydatabase


--- this grants privileges on new objects generated in new database "mydatabase"
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT ALL ON TABLES TO foo; 
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT ON ALL SEQUENCES IN SCHEMA public TO foo;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT ALL ON FUNCTIONS TO foo;


--- import DDL from SQL files (Ommitted for brevity sake)

当我尝试创建实例化 View 时，我意识到尝试从中进行选择的一个表(table_1)上存在权限错误。

我直接在CLI上尝试了一个简单的查询:

mydatabase=> select * from table_1;
ERROR:  permission denied for relation table_1

然后，我在psql CLI(连接到mydatabase数据库)上手动键入了以下内容:

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO foo;

然后，我得到响应:

ERROR: permission denied for relation table_2

这是table_1和table_2的架构:

CREATE TABLE IF NOT EXISTS table_1 (
                        td                  DATE NOT NULL,

                        f1                  REAL CHECK (f1 > 0) NOT NULL ,

                                    name                TEXT NOT NULL
                            );
CREATE UNIQUE INDEX idxu_table2_nm ON table_2 (name);

可以看出，table_1和table_2之间存在 NO 关系，因此我怀疑postgreSQL给出的错误消息实际上是红色鲱鱼(即误导)。

最后一件事。我正在使用 Docker * 来部署我的postgreSQL服务-因此上述脚本正在由docker运行。运行 docker run时创建了数据库-但是，当我以 foo用户身份登录时，尝试创建新 View (甚至在任何表上运行简单的SELECT)时，都会收到错误消息:

ERROR: permission denied for relation $table_name

我注意到的另一件奇怪的事情(当我在psql命令上运行 \z时)似乎没有显示数据库中的任何表具有任何权限:

                                                        Access privileges
 Schema |                           Name                            |   Type   | Access privileges | Column privileges | Policies

 public | mdb_company_financials_cashflow                           | table    |                   |                   | 
 public | mdb_company_financials_income_stmt                        | table    |                   |                   | 
 public | mdb_ccy_group_member                                      | table    |                   |                   | 

那么，是什么导致此许可问题，如何解决呢？

Answer 1

经过研究后，这对我有用。 psql(9.6.12)

-- login to postgres database server as postgres user.
ssh <user>>@hostname.<domain>>.com
sudo su postgres
id
psql
postgres=# create user sentry_read with login password 'sentry_read';
postgres=# du+
postgres=# \l+
-- **very important: make sure we should connect required database before we grant to user.**
postgres=# \c sentry
postgres=# \dt
sentry=# \dp SENTRY_VERSION
sentry=# select * from "SENTRY_VERSION";
sentry=# GRANT SELECT ON ALL TABLES IN SCHEMA public TO sentry_read;
postgres=# \q

[user@hostname ~]$ psql -U sentry_read -d sentry -h hostname.<domain>>.com -W
sentry=> select * from "SENTRY_VERSION";
