AlteredColumnBuilder

Allows us to force consumers to do exactly one alteration to a column.

Basically, deny the following:

db.schema.alterTable('person').alterColumn('age', (ac) => ac)

db.schema.alterTable('person').alterColumn('age', (ac) => ac.dropNotNull().setNotNull())

Which would now throw a compilation error, instead of a runtime error.

class AlteredColumnBuilder implements OperationNodeSource {

constructor(alterColumnNode: AlterColumnNode);

toOperationNode(): AlterColumnNode;

}

§Implements
