TableAmRoutine's index_build_range_scan thinks that parameter #8 is
called end_blockno, but table_index_build_range_scan and
heapam_index_build_range_scan and BRIN's summarize_range all agree
that it's the number of blocks to be scanned. I assume that this got
changed at some point while Andres was hacking on it and this one
place just never got updated.
Proposed patch attached. Since this seems like a bug, albeit a
harmless one, I propose to commit this to v12.
