    I Made New Golang Database Migration Tool▲6

    Hello HN, I've just released a new migration tool for Go that mimics the functionality of Ruby on Rails migrations. It's designed to help Go developers manage database schema changes with ease. This allows you several benefits: - Write type-safe migrations - Auto down of migrations whenever it's possible - Easy backfill even with business logic because it's Go code - Painless integration with existing schema - sql.DB compatible and driver agnostic (it uses your driver) I have a pretty complete API to manage Postgres schema and I am working on the SQLite one (a little more complicated due to…

    I Wrote a Book on PostgreSQL for Rails▲47

    Hi HN. As a backend developer using PostgreSQL and Ruby on Rails for more than 10 years, around 3 years ago, I caught a spark to learn as much as I could about how to operate high performance, scalable, and reliable PostgreSQL databases.

I've been fortunate to give presentations in both the PostgreSQL and Rails…
