Here are some comments about the 4th patch.
1) Compiles without warnings, passes make check.
2) s/ginFinshSplit/ginFinishSplit
3) Server crashes when trying to create a gin index index creation (see
example of previous email with pg_trgm). Here is the backtrace of the crash:

Test has been done on OSX 10.9.
This is all I have for now... I will have a look at the code later, as this
patch changes quite a bit the internals of gin, it is going to take a
little bit of time.
Thanks,
