> MySQL and PostgreSQL have converged in terms of features and performance Is there CTEs in MySQL yet? What about binary JSON and indexes on that? How is implementing arrays and aggregate functions beyond simple arithmetic going?

Can DDL statements be rolled back, so I wouldn't have to pull my hair out during development after running migration I'm working on, if it happens to have a typo?
