I plan to support most of postgres features. Preplanning or preparing 
queries is already done using prepare() method of PGCommand just like in 
Npgsql. Cursors also should be available to users. In case of functions 
I assume native D functions linked to postgres. These must be compiled 
to shared library and loaded within server but AFAIK shared library 
support is not complete in D2 (maybe I'm misinformed?).
Also there will be support for other advanced features like asynchronous 
notifications (using NOTIFY channel, payload; syntax).

Non query prepared statements are already working. For general API, I 
need to finish query result handling and binary formatting of compound 
types and arrays. Then I will be working on ORM API.

I will post source code when result handling is done :)
