I like the idea of being able to track multiple data migrations or schema changes in parallel. We do currently support basic point-and-click DDL, and the data gets migrated when you (for example) set up a linked table based on some columns from an initial table, but we don't really have a way to track multiple such requests in one view.

I suppose one general solution would be to provide a UI for `pg_stat_activity` or other similar system tables that lets you filter easily.
