Minor wording change

"pool in a SQL Database" gives the impression that the pool is a child of a database, which is incorrect.
Also removed unnecessary line breaks.
Added PremiumRS as an Edition value and re-arranged acceptable values in logical order.
Set -Tags example with code formatting and changed a tag name to include a space, to illustrate the possibility.
