Postgres schema changes are still a PITA
From what I know, there is only one project that tries something close to this: the relatively recent Reshape. It uses Postgres views to expose the two versions of the schema and triggers to upgrade/downgrade the new data. It doesn’t do the constraints part as described above, but shows that this approach is possible. Combined with the Xata pull request based workflow, I think the ideal system described above is possible!

Conceptually how do you handle deploys of SQL related things (table definition, scripts, stored procs etc) in a CI/CD way?
My idea is not unique. Reshape is similar, but bigger in scope.

The operational relational schema paradigm
This is precisely what I did for my automated zero-downtime migration tool and it works pretty well: https://github.com/fabianlindfors/reshape. At least for Postgres, simple views like these have almost no overhead as queries are simply rewritten for the underlying table.

Type-safe Data Access in Go using Prisma and sqlc
Now, why not use an ORM? I've seen performance issues too many times with ORMs. I prefer writing my own SQL to avoid surprises. After all, I know the database schema and writing code for a specific purpose very often leads to better performance than generic code. ORMs have to support all kinds of database schemas. I only have to support mine. Having successfully used Knex.js in NodeJS (a popular query builder) in the past, I know writing SQL queries myself is not hard and provides very good performance.

Why SQL is right for Infrastructure Management
SQL is an old, irregular language to work with, but it is better known than HCL and SQL already has it's own Pulumi/CDK in the form of every ORM with introspection (like Javascript's Prisma, Python's Django, Go's XO etc) and QueryBuilder (LINQ, Knex, etc) in whatever programming language you prefer. You probably already know it.
