Thanks! And done.

For the huge pages setup documentation, I considered sending stderr to
/dev/null to eliminate the LOG from the output, but I opted against
that. That would've looked like this:

postgres -D $PGDATA -C shared_memory_size_in_huge_pages 2> /dev/null

Otherwise, there aren't any significant changes in this version of the
patch besides the name change.
