Update 2

As of August 28th, 2025, Expert LSP has been released: https://github.com/elixir-lang/expert

Although still a work in progress, the plan is for the other three LS implementations to be archived. I may try to come up with a new way to track Expert's featureset, but I would probably contribute that back to Expert as documentation.

Update

As of August 15, 2024, it's been announced that the three projects bein compared here will soon merge! See the official Elixir blog post for more details: https://elixir-lang.org/blog/2024/08/15/welcome-elixir-language-server-team/

error: gpg failed to sign the data fatal: failed to write commit object

Terraform vs PostgreSQL RDS

Thanks to new resources (postgresql_default_priviledges) and some fixes Terraform can now add new databases and manage ownership / access to them.

This example creates new database and two users. You can use owner to create new tables and run migrations and user for normal read/write access to database.
