* I've added short explanation of this to the documentation.
* Removed no longer present data structures from typedefs.list of the
first patch.
* Moved GIN support patch to number 3. Seems to be well-isolated and
not very complex patch. I propose to consider this to 12 too. I
added high-level comment there, commit message and made some code
beautification.
