Merge 26b6c6e883 into 3c2356b9b4

* Remove install for shards

shards is not available as a Homebrew package. Instead, it comes with
the crystal package.

<https://crystal-lang.org/reference/1.12/man/shards/index.html#installation>

* Fix postgresql package name

* Add createdb

Fixes initial error:

    FATAL:  database "<user>" does not exist

<https://stackoverflow.com/a/17936043>

* Clone repo before PostgreSQL setup

The PostgreSQL setup uses config files from the repo.

* Fix PostgreSQL name in headings

* Give PostgreSQL role login permissions

Fixes an error upon running the first script:

   FATAL:  role "kemal" is not permitted to log in

* Remove nonexistent script

* Use make for Invidious setup
