As a starting point, you can look at these two functions:

src/backend/optimizer/path/indxpath.c : find_usable_indexes()
src/backend/optimizer/util/pathnode.c : add_path()

Hope this helps.

TIP 9: In versions below 8.0, the planner will ignore your desire to
       choose an index scan if your joining column's datatypes do not
       match
