Hard to understand what you're proposing... A language with a type system that brings its own serialization format (so you don't have to deal with the fact that SQL and friends have no good way to represent polymorphic data types such as enums or interfaces)? Or a language with a runtime that uses disk as main memory (this seems to be the implication from 'program can be terminated and resumed transparently')?

Postgres has enums.

Postgres has a feature called "enums", but they are not polymorphic--all values for a given Postgres enum must have the same type.
