I am a student in China. I have read some source code of postgreSQL, though only a little. I think maybe there is typo in this file: src\backend\catalog\index.c. At line 649 in v9.2.0, line 653 in V9.2.2. The sentence is " *indexInfo: same info executor uses to insert into the index", I think it should not be 'same', but 'some'.
I am not sure if my thoughts is right.
Sorry for my poor English.
Good Luck From Beijing!
