22496	Data migrations are not transactional (except on Postgres)	Shai Berger	nobody	"In e74d2183c28467aefc0b87e3fa6d405dbfdea82c (master) and 9bf890f6f9d137d5b86fd9a6a38fb11c5d21b1af (1.7.x) schema editor was made not to open transactions for backends that cannot roll back DDL. However, there is nothing else that starts transactions in migrations, even if they are data migrations -- so now, of the backends in core, migrations are only transactional on PostgreSQL.

This is a spin-off from #22483."	Bug	closed	Migrations	dev	Release blocker	fixed	oracle mysql sqlite	Aymeric Augustin Andrew Godwin	Accepted	0	1	1	0	0	0
