[postgis-users] Versioning system for PostGIS

[Paul Ramsey]

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!
