That looks mostly like you've added support for postgres "extras", not (inherent) "postgres goodness". Not that adding support for "extras" is a bad thing -- but in the context of "adding support for postgres sql" -- that seems somewhat orthogonal? (I'm not saying it is wrong for rails to approach postgres this way, just that the approach doesn't seem to change the way rails (afaik) approach databases: logic should be in rails, not in stored procedures and views (which is where it would make sense to place logic, if you design with "database first")).

Interesting link, either way.
