Hi,

I have written microvacuum support for gist access method.
Briefly microvacuum includes two steps:
1. When search tells us that the tuple is invisible to all transactions it is marked LP_DEAD and page is marked as "has dead tuples",
2. Then, when insert touches full page which has dead tuples it calls microvacuum instead of splitting page.
You can find a kind of review here [1].

Patch is in attachements. Please review it.
