SQL 服务器的 AWS RDS - 如何创建启动存储过程？

Question

We are moving to RDS and one of our apps needs access to tempdb and I am trying to figure out the best way to create a startup job that works with RDS. Currently we are able to create a stored proc that sets up the necessary permissions in the master database and use the EXEC sp_procoption 'AddPermissionsToTempDb', 'startup', 'true' command to set it to start at boot.

In RDS however we are not able to create stored procs in the master database. I tried creating the stored proc in a user-owned db but when I then try to create the startup job with EXEC sp_procoption 'mydb.dbo.AddPermissionsToTempDb', 'startup', 'true' it says it can't find the stored procedure or I do not have permission... Is there another way to accomplish this on RDS?

Was able to find a solution based on Jeroen Mostert's comment so credit goes to them. Here is the full query I used to create the startup job to grant permissions to a list of users to create, control and execute stored procedures on tempdb on an AWS RDS SQL Server instance:

USE msdb
go

declare @job_name varchar(50)
set @job_name = 'AddTempDBPermissionsOnStartup'

exec dbo.sp_delete_job @job_name =  @job_name

declare @sql varchar(max)
select @sql = '
Declare @Users Table (username varchar(100) )
insert @Users(username) values (''[user1]''),
(''[user2]''),
(''[user3]'')

use tempdb
CREATE ROLE sp_executor GRANT EXECUTE TO sp_executor
CREATE ROLE sp_manipulator 
GRANT CREATE PROCEDURE TO sp_manipulator
GRANT CONTROL TO sp_manipulator

DECLARE @username as NVARCHAR(100);
DECLARE User_Cursor CURSOR FOR  
    SELECT * from @Users
OPEN User_Cursor;
FETCH NEXT FROM User_Cursor INTO @username;
WHILE @@FETCH_STATUS = 0  
    BEGIN
        PRINT @username
    IF EXISTS(SELECT * FROM [tempdb].sys.database_principals WHERE type_desc = ''SQL_USER'' AND name = @username)
        PRINT ''  - user already exists''
    ELSE
        BEGIN
            PRINT ''  - creating user''
            DECLARE @Sql VARCHAR(MAX)
            SET @Sql =
            ''USE Tempdb'' + char(13) + 
            ''CREATE USER '' + @username + '' FOR LOGIN '' + @username  + char(13) +
            ''EXEC sp_addrolemember sp_executor, '' + @username + char(13) +
            ''EXEC sp_addrolemember sp_manipulator, '' + @username
            EXEC (@Sql)
        END
    FETCH NEXT FROM User_Cursor INTO @username;
END;
CLOSE User_Cursor;
DEALLOCATE User_Cursor;
GO

--Add a job
EXEC dbo.sp_add_job
    @job_name = @job_name ;

--Add a job step to run the command
EXEC sp_add_jobstep
    @job_name = @job_name,
    @step_name = N'job step',
    @subsystem = N'TSQL',
