Require Primary Key
In almost all cases, each table needs a primary key.
In MySQL, the InnoDB storage engine always creates a primary key if you didn't specify it explicitly or didn't create a unique key, thus making an extra column you don't have access to.
How the rule works
Bytebase considers this rule to be violated if the SQL tries to create a no primary key table or drop the primary key. If the SQL drops all columns in the primary key, Bytebase also considers that this SQL drops the primary key.
Support database engine
Support for PostgreSQL is coming soon.
