REVOKE ALL on AWS RDS instances

[krogon-dp]

Hi, Is there any specific reason this provider uses REVOKE ALL statement?

https://github.com/terraform-providers/terraform-provider-mysql/blob/master/mysql/resource_grant.go#L120

Once this command is OK when used with specified database name, RDS does not like this when used with * all databases.

mysql> grant all on test.* to 'aaa'@'%';
Query OK, 0 rows affected (0.05 sec)

mysql> revoke all on test.* from 'aaa'@'%';
Query OK, 0 rows affected (0.04 sec)

mysql> grant select on *.* to 'aaa'@'%';
Query OK, 0 rows affected (0.04 sec)

mysql> grant all on *.* to 'aaa'@'%';
ERROR 1045 (28000): Access denied for user 'rdstest'@'%' (using password: YES)

Why not to remove the same privileges that resource is holding?

This issue still exists and is a blocker to any editing grants or removing any user on AWS RDS/Aurora databases.

The root of the issue is REVOKE ALL is not allowed and should be replaced by a comma separated list.

It should be noted that REVOKE ALL also interferes with multiple resource "mysql_grant" on the same level.
