PostgreSQL dev setup on Arch Linux using podman

Introduction

This document summarises my learnings from setting up a postgres container on arch linux for dev - no prod. I will also touch on using psql and vim-dadbod-ui to interface with the DB. There's also dbeaver, which is the shotgun epquivalent of DB tools (= fire and forget, easy to use), which I won't cover here for that reason. My goal was specifically to set up a local dev env with the limited knowledge I have of docker containers and DBMS in general.

Installing PostgreSQL

I did not want to install postgres on my system directly, although I could run it on demand and kill when done, it seemed cleaner to have a layer of separation. Instead I only installed postgresql-libs (aka libpq) solely for psql, which is essentially a postgres read-eval-print-loop (REPL).

How to set up LazyVim/Neovim for Godot on Linux

Please note: This setup if for gdscript, not csharp.

External Editor Setup

When clicking on a button or error message that opens a gdscript file in Godot, we want it to open in nvim instead. There are many ways to do this, this is mine:

• Create a bash script nvim-broadcast with this content:

/* USAGE EXAMPLE:
    const mountElem1 = document.body;
    const nodes = htmlWindowContent(
            { fontSizes
            , defaultFontSize
            });
    const elems = mount(nodes, mountElem);
    
    function htmlWindowContent({fontSizes, defaultFontSize}) {
        return m(DIV, {id: ID_TP_CONTENT},
