I think people have been answering a question that is different from
what you are asking.
It looks to me like you are asking something to the effect: *After*
upgrading to Postgres 10 - will I use more disk space than 9.5?
I don't believe that there have been significant changes in storage
space allocation between 9.5 and 10, so your tables should be the same
size. e.g I frequently create a database using pgbench scale 100. it has
used 1.5 GB of disk for all the version of Postgres that I have used
(and that is quite a few)!
