When I create a new database instance in Google CloudSQL, it creates a default user called postgres. I created another user and when I tried to remove the default postgres user I received a message: Can not remove a System user.
Some months ago I could remove the default user without problems. Did google change anything in CloudSQL? How can I remove the default user?
The postgres user is part of the cloudsqlsuperuser role. Because Cloud SQL for PostgreSQL is a managed service, it restricts access to certain system procedures and tables that require advanced privileges. In Cloud SQL, customers cannot create or have access to users with superuser attributes, including the postgres user. This is documented on the PostgreSQL users documentation page.

Since the cloud-sql-proxy already forces individual user authentication with the database through a users iam account, and allows specifying read / write permissions, it seems potentially pointless to also have an individual database accounts for each user as well.
For security, is it necessary to have a database user per dev when using cloud-sql-proxy, or is it fine to just have one database user, since they are already authenticated by the time they can enter a database user / password anyways. I'm not a server dev or a DBA, so I thought it best to ask.
In fact, you have 2 levels of permissions
Cloud IAM allows you to access to Cloud SQL product or not
Database user management allows to log into the db engine and to get the db engine permission (access to a specific schema, one schema per developer, on the same SQL instance for instance).
The hosted database engine are based on MySQL, PostgreSQL or SQL Server. All those databases have their legacy user authentication in place. You have to deal with.
I have a Google Cloud SQL server running MySQL that is used by low technical knowledge users to import csv's to a MySQL database. They use the Import function built into GC SQL. However, there are several databases and I would like to limit access to a database to each user.
Here is the menu that I refer to: https://i.imgur.com/LyX7Wbk.png
I already tried assigning a IAM Role with less access but everything excep SQL Admin greyes out the Import option. SQL Admin gives complete access to even delete the instance so its definitely not an option.
Any help would be greatly appreciated.
You can't. Indeed, IAM role allow you to control access to GCP component. Here, your requirements is to administrate user that access to specific database schema, which is the role of DBA.
The only solution is to build something on top of Google API for limiting/controlling access.
I have successfully created an AWS RDS SQL Server 2016 instance. I specified a master user name and password. I was able to log into that instance via SSMS using the master user name and password. I then created a database. However, it seems the master user doesn't have any permissions to do anything in that database, such as creating any schema objects. What do I have to do to have essentially db_owner permissions in the database I just created?
Going to sound funny, but try resetting the master user password. Don't know why it works, but it worked for me with a similar problem.

I wanted to setup an RDS instance store data for reporting. I have scrips that run different rest calls against certain sites that require bulk admin privilege on the back end because they dump their rest call data into a csv and then do a bulk csv insert into Sql Server SE. In my local environment setting up a user for my scripts to use with bulk admin privileges was easy. However, I couldn't seem to figure out how to do it in RDS. I opened a ticket with Amazon and they suggested writing a policy for it. So I figured I would ask here if this is possible and possible alternatives? If bulk/system admin privileges are out of the question in RDS I guess I will just have to use an AWS EC2 instance with Sql Server set up on it.
Bulk insert is not possible with RDS. The data_file parameter of the BULK INSERT command must refer to a file accessible by the machine running SQL Server.
Also, RDS does not support the bulkadmin server role.

I need to create a new MySQL user with limited permission on an existing Amazon RDS instance. After encountering a couple error messages I was sort of able to do this using the official MySQL Administrator tool and the user now appears in the list. However, I'm unable to assign any schema privileges as all the users are greyed out. I'm logged in as the "master user" created when the instance was launched. Not sure where to go from here. I do have the RDS command line tools installed but wasn't able to track down anything there either. Ideas
Your best bet is probably to connect to the database with a mysql command line client and call the SQL commands to create a new user and assign him privileges.
For instance, you might run something like this:
mysql -u [your_master_username] -p -h YOURRDSENDPOINT.rds.amazonaws.com
CREATE USER 'jeffrey'#'%' IDENTIFIED BY 'somepassword';
GRANT SELECT ON [your_database].[some_table] TO 'jeffrey'#'%';
On windows you could use the mysql.exe client, wherever that is.

I know this thread is a couple of years old and well I keep finding it so I wanted to get an update out about the AWS RDS and User Permissions.
You cannot use GRANT ALL for any user with an RDS. When you use the GRANT ALL statement you are also attempting to provide Global (as AWS Calls them Super Permissions) and with the way that the AWS RDS System is setup they do not allow assigning of Global Options to users.
You have to break out the Permissions to the following:
GRANT SELECT,INSERT,UPDATE,DELETE,DROP on
This will allow your user to be able to connect to the RDS once the security settings are setup to allow access from your EC2 Instances or from the Internet.
Hope this information helps anyone else that is running into the same issues that I was seeing with the AWS RDS Systems.

I created like this:
CREATE USER 'jeffrey'#'localhost' IDENTIFIED BY 'somepassword';
GRANT SELECT ON mydatabase.* TO 'jeffrey'#'localhost';
But then, AWS rejected to login to that user. And I tried to change Admin privileges, but not success. And I change 'localhost' to '%' through mysql workbench. (or you can remove the user and recreate) like :
CREATE USER 'jeffrey'#'%' IDENTIFIED BY 'somepassword';
GRANT SELECT ON mydatabase.* TO 'jeffrey'#'%';
Then only I was able to loggin through this new user.
In addition:
Once you done this change, then your database allowed to connect from any ip. If you need to improve the security and restrict the accessing ip (Ex: if this is a staging database), you can set the bind-address in my.cnf file in your server.
bind-address = your.ip.add.ress

I had the most success using MySQL Workbench and executing raw SQL against RDS:
CREATE USER 'foo'#'localhost' IDENTIFIED BY 'password';
The bigger problem was permissions. Initially I tried:
Grant ALL on *.* to 'foo'#'localhost'
... which results in an Access Denied error.
Error Code: 1045. Access denied for user 'foo'#'%' (using password: YES)
The troublesome permission is "super" which RDS doesn't give me, and in turn I can't grant. As a result, I'm stuck doing permissions by hand:
Grant SELECT on *.* to 'foo'#'localhost';
Grant INSERT on *.* to 'foo'#'localhost';
Grant CREATE on *.* to 'foo'#'localhost';
I have used mySQL workbench and it works fine. just go to management/Users and Privileges, press "Add Account" button bottom left, and configure. You cannot give SUPER privileges, but most of the rest
