Steps to Reproduce:

1. install vscode flatpak
2. install remote-containers extension
3. install podman@latest and podman-compose@devel, provide shims to invoke from within flatpak
4. create a new devcontainer config via the default "node.js + postgres" wizard
5. update config to work around podman compatibility issues (below)
6. try to open the container & see the above logs

Alternatively (sorry, only useful on a steam deck):

1. install https://github.com/hunterloftis/dotfiles on a steam deck
2. open ~/test/node-pg in a devcontainer
3. see the above failure

        "remoteUser": "node",

	"runArgs": [
		"--userns=keep-id"
	],
	"containerUser": "node" // the value needs to match the value of "remoteUser"
