We previewedsome of these features back in July and August. "A most-requested feature by application developers for several years,'UPSERT' is shorthand for 'INSERT, ON CONFLICT UPDATE', allowing newand updated rows to be treated the same. UPSERT simplifies web andmobile application development by enabling the database to handleconflicts between concurrent data changes. This feature also removesthe last significant barrier to migrating legacy MySQL applications toPostgreSQL."
