Review comment:
We can have the foreignkeys kept under foreignkey table wrapper but the
reference such as foreignkey db/table and key name in parent table wrapper. It
will be useful when getForeignKeys is called with null for foreign db/tbl. I
just want to confirm if this a frequent call with null as input. If yes, then
let's do it, if not ignore this comment.
