How not to change PostgreSQL column type
My thoughts exactly. It's surprising that external online schema change tools for Postgres have only become a thing fairly recently! The only two I'm aware of are:
* pgroll: Written in Golang, first commits June 2023. https://github.com/xataio/pgroll
* pg-osc: Written in Ruby, first commits Dec 2021. https://github.com/shayonj/pg-osc
Meanwhile over in the MySQL and MariaDB ecosystem, external OSC tools have been around for quite some time, starting with oak-online-alter-table over 15 years ago. The most popular options today are pt-online-schema-change or gh-ost, but other battle-tested solutions include fb-osc, LHM, and the latest entry Spirit.

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.
