What were you trying to do (and why)?

I was trying to install Postgres.app.

What happened (include all command output)?

$ brew install postgres-unofficial
==> Downloading https://github.com/PostgresApp/PostgresApp/releases/download/v2.5.12/Postgres-2.5.12-10-11-12-13-14-15.dmg
==> Downloading from https://objects.githubusercontent.com/github-production-release-asset-2e65be/3946572/9deef084-868f-439e-9741-db6d13212ec6?X-Amz-Algorithm=AWS4-HMAC-SHA256

==> Installing Cask postgres-unofficial
==> Moving App 'Postgres.app' to '/Users/thoran/Applications/Postgres.app'
🍺  postgres-unofficial was successfully installed!

When attempting to run it, I see a dialog with the following:
"Postgres.app can't be launched
Please move Postgres.app to your Applications folder.

• use Finder to move the app
• don't place it in a subfolder
• don't change the app name

OK"

What did you expect to happen?

I would think that if an app refuses to run if not in /Applications (and there are others, megasync being another) that a formula should know this and allow for an automatic exception if a flag is set. I may refuse to allow for such an exception I suppose. If there is otherwise no necessity for apps to be installed in /Applications and it will refuse to run otherwise that's an app developer issue, but at least we should be able to manage as well as are able at the installer level. I believe that some apps really can't run unless in /Applications due to some constraint on certain kinds of apps imposed by Apple. The suggested flag is --app-dir-strict=false as the default. If I set it to --app-dir-strict=true, then it will refuse to install in /Applications and install as per --app-dir anyway or refuse to install anything, since there's no point I suppose.

Sounds like a non_relocatable: key for the app stanza might be a good idea.

@gromgit Agreed. @Homebrew/cask any thoughts?

Excellent idea.
