Whose pick this was

Change a schema without taking the site down
Then read the schema that is actually deployed, rather than the one implied by the migration folder or an ORM's cached types. Structure: columns, types, the nullable nobody remembers, the indexes that already exist. Set `readonly = true` on `execute_sql` and this can look at everything and change nothing.
