This means that there are theorems you can not prove deriving from the axioms.

It means that perhaps you can find unprovable relational theorems. Nothing less and nothing more.

No you don't understand anything. It does not have any relationship with what Godel said.

BTW have you readen The Third Manifesto?

It has many pages devoted to the integration of The Relational Model with procedural programming (stored procedures). Just what you want to address.
