Hi
On moving from postgres 9.5.4 to postgres 10.x we have to do data
migration.
Can some one let me know will the disk space requirement remain same for
same set of tables with same number of rows in postgres 10.x and postgres
9.5.4 ?
Thanks,

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)!
Cheers
Mark

Hi Debraj,
You can use pg_upgrade utility from Postgresql. This works with inplace option. Look at this link below for more details.

This option is also be the fastest for upgrading from 9.5 to PG10

Yes.
What will be the disk space requirement for space for same set of data in
9.5 and 10? I am asking this as I am guessing since we have to do data
migration so there may be some change in data format.

Hi Debraj,
I recently upgraded my postgres from 9.5 to 10.3 using pg_upgrade and it
was smooth. There is no separate disk space requirement for migration of
data .
Also before migration you can try "check " option for dry run of migration.
(not actual migration , data will be untouched).Below is command
/usr/pgsql-10/bin/pg_upgrade --old-bindir=<> --new-bindir=<>
--old-datadir=<> --new-datadir=<> --check

How fast is fast? Does it need to rewrite all the data (would take a while
on a Really Large Database), or just change a bit of metadata?

You will create a new data directory for 10 and the data from 9.5 will get moved to that new folder after the upgrade. The metadata info in the catalog will get updated accordingly to pg10.
At the end of the upgrade, the 9.5 folder can be dropped after making sure everything is working. This script is also get generated by pg_upgrade.
thanks,Suresh Neravati.

I think been are going off the topic in this thread. My initial question was
Can some one let me know will the disk space requirement remain same for
same set of tables with same number of rows in postgres 10.x and postgres
9.5.4 ?
