PostgreSQL: Migrating from int to bigint

Resources

PostgreSQL zero-downtime migration of a primary key from int to bigint (with Ruby on Rails specific notes)

• This approach requires setting up a PostgreSQL trigger to keep the mirrored bigint column in sync with the existing int column until it is time to swap them out.

Se você quiser adicionar mais algum tópico deixe seu comentário, o objetico é facilitar para os iniciantes ou aqueles que buscam dominar JavaScript, quais tópicos são importantes para dominar JavaScript.

São tópicos para quem sabe o minimo de JavaScript (declarar variáveis), a ordem em que eles aparecem são por importância para o dominio como um todo. Mesmo que você já tenha experiência com JS, recomendo que leia os links de cada tópico para fortalecer suas bases teóricas e ter um comportamento mais profundo da linguagem.

"""A quick benchmark comparing the performance of:

- msgspec: https://github.com/jcrist/msgspec
- pydantic V1: https://docs.pydantic.dev/1.10/
- pydantic V2: https://docs.pydantic.dev/dev-v2/

The benchmark is modified from the one in the msgspec repo here:
https://github.com/jcrist/msgspec/blob/main/benchmarks/bench_validation.py

I make no claims that it's illustrative of all use cases. I wrote this up
