Changing Tires at 100mph: A Guide to Zero Downtime Migrations
Postgres has some less robust tooling, at least both of these carry the "experimental" tag:

Show HN: Zero-downtime PostgreSQL migrations for Ruby on Rails
This is very cool! I no longer work on Rails on daily basis, but would have loved to have this.
I built something similar called `pg-osc` / `pg-online-schema-change` for PostgreSQL workloads. It does zero downtime migrations using triggers and shadow table.

Also love that this is written in Ruby :). Going to check it out on some side projects.

Cool stuff! Do you have any thoughts about how this compares to https://github.com/fabianlindfors/reshape?

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.

Changing Tires at 100mph: A Guide to Zero Downtime Migrations
Anybody interested in this subject might also be interested in a tool for Postgres I’ve been working on, Reshape: https://github.com/fabianlindfors/reshape. It aims to fully automate away all the pain and manual steps zero-downtime migrations normally requires :)
