Hold on right there. No one is talking about implementation, much
less about 'direct image implementation', whatever it is. Please
state clearly what the difference is between two expressions describing

What's that supposed to mean ?

So do both the relval and the SQL object descriptions. It's, like, a trivial observation.

That does not make any obvious sense.
