I think "best_inner_indexscan()" in the following comment in tidpath.c is obsolete.
* There is currently no special support for joins involving CTID; in * particular nothing corresponding to best_inner_indexscan(). Since it's * not very useful to store TIDs of one table in another table, there * doesn't seem to be enough use-case to justify adding a lot of code * for that. How about s/best_inner_indexscan()/parameterized scans/?
