I have a request to supply business owner with both the available size of DB as well as the used size of the DB. I have been able to locate the used size, but I don't see any way to query the available size (used + unused space). How can I find that in PSQL?

There is no unused space in PostgreSQL like this. It will use all the available space on disk that you give it. It is not like Oracle where you can reserve segment sizes.
So for this, you'd just monitor your available space on disk for the filesystem that PostgreSQL is using.
