How deep does this have to be? The simplest versioning system is just:
create table foo;
create table foo_history;
Then add update/insert/delete triggers on foo that fill in the deltas
in foo_history. There used to be code in contrib/ that did this, but
I think it got removed.
"Versioning" is a loaded and conflicted term, more definitions are
required to know what you mean by it!
