The only option is pg_upgrade in link mode.  Also, you might want to
upgrade to a newer version of Postgres than 9.6.

Upgrade from 9.2 to 9.6 without space

Hello good day.

I am writing why I need guidance regarding a version upgrade in Postgresql. I have a server with 85% of the disk occupied only in the / var / lib / pgsql / data folder and when doing an upgrade it drops because it does not have space to create the new / var / lib / pgsql folder /9.6/data in your process.
So I need to know if there is any procedure to upgrade without making a copy since I do not have space for another folder of the same size.

PS: I am upgrading from 9.2 to 9.6

I hope they can help me
From already thank you very much

pg_upgrade can do that if you use link mode (pg_upgrade -k).  It is
strongly recommended to make a snapshot of the data directory before the
upgrade, so that you can roll back to the original if things go wrong.

Going up only to 9.6 means that you will be pressed to move to a more
recent version soon, since 9.6 goes out of support at the end of the
year.  Why not go straight to, say, 12?

I suggest to add more storage space.

The pgsql-es-ayuda@lists.postgresql.org can help you if you would like
to discuss in Spanish.
