I want support not just for PostgreSQL native datatypes, I want ActiveRecord support for adding my own custom datatypes.

You can pretty much do that right now (and have been able to for years) with composed_of: http://api.rubyonrails.org/classes/ActiveRecord/Aggregations... (search on that page for it)

The problem is that custom pg types are represented as strings in ActiveRecord < 4.0.

In AR 4.0, you can have ActiveRecord automatically cast them to a different type.

composed_of is the "other half" of what I want. I don't want to use custom ruby classes, I want to use custom Postgresql types.

Turns out support for that's in 4.0 too!

That's in ActiveRecord 4.0 as well!

Take a look at @tenderlove's comment down below about the actual implementation (as opposed to my crappy one in the issue body).

You can say what you want about rails, but i really admire the pace they make progress.

Rails is the new Java.
