Re: Postgres 10 disk space requirement compared to postgres 9.5.4

Hi Debraj,

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

PostgreSQL: Documentation: 10: pg_upgrade

PostgreSQL: Documentation: 10: pg_upgrade

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

Thanks,

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,
