Add DISOWN DATABASE support #110

Open pixelspark opened 6 years ago

pixelspark commented 6 years ago

DISOWN DATABASE removes the owner for a database, so that the only modifications that can be made to the database's contents are those allowed by the grants table. After being disowned a database cannot be removed anymore (perhaps allow DROP DATABASE from a template so it can be made conditional?)

pixelspark commented 6 years ago

Perhaps implement a more generic 'transfer ownership to [user]' mechanism (where [user] can be 'nobody').

pixelspark commented 6 years ago

Proposed syntax is LEAVE DATABASE x TO y; to transfer, or LEAVE DATABABASE; to disown it forever. TBD: Disowning forever is only allowed when there is at least one (valid?) entry in the grants table.
