postgresql - PGsql ：授予用户对模式的每一个权限

Question

我不知道如何将每一项权利授予特定用户，我希望用户拥有架构上的每一项权利：

• 在现有表上插入、删除、更新、选择……

我试过做：

    GRANT ALL PRIVILEGES ON SCHEMA schema to "user";
    GRANT ALL ON SCHEMA schema to "local_518561";
    GRANT ALL PRIVILEGES ON table schema.table to "user";
    GRANT ALL ON table schema.table to "user";

查询返回成功，但每次我使用其他用户时，我都会收到权限不足错误。

Answer 1

GRANT ALL PRIVILEGES ON                  SCHEMA schema_name TO role_name;
GRANT ALL PRIVILEGES ON ALL TABLES    IN SCHEMA schema_name TO role_name;
GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA schema_name TO role_name;

Answer 2

如果您使用的是 PostgreSQL < 9 的版本，您可以使用以下存储过程来管理表和序列的权限：

CREATE OR REPLACE FUNCTION grantTablesOfSchema (user VARCHAR,
   permissions VARCHAR, schema VARCHAR) RETURNS VARCHAR AS
$body$
DECLARE
  regActual   RECORD;
  numTables   INTEGER;
BEGIN

   numTables := 0;

   FOR regActual IN
      SELECT tablename FROM pg_tables WHERE schemaname = schema
   LOOP
      numTables := numTables + 1;

      EXECUTE 'GRANT ' || permissions || ' ON ' || schema || '.' || regActual.tablename || ' TO ' || user;
   END LOOP;

   RETURN 'Tables: ' || numTables::VARCHAR;
END;
$body$
LANGUAGE 'plpgsql';


CREATE OR REPLACE FUNCTION grantSequencesOfSchema (user VARCHAR,
   permissions VARCHAR, database VARCHAR, schema VARCHAR) RETURNS VARCHAR AS
$body$
DECLARE
   regActual       RECORD;
   numSequences    INTEGER;
BEGIN

   numSequences := 0;

   FOR regActual IN
      SELECT sequence_catalog, sequence_schema, sequence_name 
      FROM information_schema.sequences 
      WHERE sequence_catalog = database AND sequence_schema = schema
   LOOP
      numSequences := numSequences + 1;

      EXECUTE 'GRANT ' || permissions || ' ON ' || schema || '.' || regActual.sequence_name || ' TO ' || user;
   END LOOP;

   RETURN 'Sequences: ' || numSequences::VARCHAR;
END;
$body$
LANGUAGE 'plpgsql';

以及一个使用示例：

CREATE USER user1 WITH PASSWORD 'user1@user1?user1';
GRANT CONNECT ON DATABASE database1 TO user1;
GRANT USAGE ON SCHEMA schema1 TO user1;

SELECT * FROM grantTablesOfSchema ('user1', 'SELECT, UPDATE, INSERT, DELETE', 'schema1');

SELECT * FROM grantSequencesOfSchema ('user1', 'ALL', 'database1', 'schema1');

相反，如果您的 PostgreSQL 版本 >= 9：

GRANT ALL ON ALL SEQUENCES IN SCHEMA schema1 TO user1;
GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA schema1 TO user1;

Answer 3

答案在于序列，如果您不授予表和序列（如果有）的权限，则您无法插入。
