IMO this will be extremely challenging, unless we could add appropriate
hooks in the core engine. Even then, finding the right set of hooks may
turn out to be a challenge itself.

What we could do though is to make datanodes to be standard PostgreSQL + an
extension. The coordinators can still be modified version of Postgres. This
will still be quite comforting because the real data will reside on
standard PG instances and accessed via standard API.
