Hi Andrey,

I've spotted in the commitfest that the cfbot complained [1], so I've took a
quick look. It appears that recent preparation work for the index prefetch
(shifting the responsibilty of the index scans to the tableam alone), commit
ddce1da5b1b1 removed the IndexFetchTableData and table_index_fetch_{begin,
tuple,end}. To my understanding this new stuff - that is:
* table_fetch_tid() -> heapam_fetch_tid()
* table_tuple_fetch_row_version() -> heapam_fetch_row_version()
still follows LP_REDIRECT/HOT, so it should be OKay-ish, but please take a
deeper view if possible.

Attached v6fixup is patch that fixes the compilation issue, and passes
CI tests for
me (I didn't want to modify the v6 patchset to make review easier).

-J.
