Minor comment: since you removed the ----- lines from the index_create
header comment, I think pgindent will mess up the alignment for that
comment, which probably will not be very nice.  Same in
index_update_stats.  Otherwise, nice work!  I will update my relminxid
patch to this and re-submit.

No, left-justified comments aren't subject to reindenting (correct Bruce?)
Certainly there are plenty of other function header comments that don't
have any ---.
