Upgrade PG9.6 to PG10

Here an asciicast for you. With less do more :)

Upgrade from PSQL9X to PSQLXY with pg_upgrade (OpenSUSE)

Upgrade from PSQL9X to PSQLXY  

with pg_upgrade (OpenSUSE)

- Step 1
Proof which Extension you are use in your Database

- Step 2
Install all PSQL 9.4 Packets - all Extension like ip4r or oraclefce too

- Step 3
shutdown the old one DB (9.3)
systemctl stop postgresql

- Step 4
Move the old DATA-Folder (/var/lib/pgsql/data) and create a new one

Moving
mv /var/lib/pgsql/data/ /var/lib/pgsql/data93
Create new Folder
mkdir /var/lib/pgsql/data/
PSQL Rights
chown postgres:postgres /var/lib/pgsql/data/

- Step 5
PSQL 9.4 start and stop - only to reinit the DATA-Folder
systemctl start postgresql
systemctl stop postgresql

- Step 6
Change User to postgres
su - postgres

- Step 7
Execute pg_upgrade as user postgres
pg_upgrade -d /var/lib/pgsql/data93 -D /var/lib/pgsql/data -b /usr/lib/postgresql93/bin -B /usr/lib/postgresql94/bin

Failure Situation:

                                                            ok
Checking for presence of required libraries                 fatal

Your installation references loadable libraries that are missing from the
new installation.  You can add these libraries to the new installation,
or remove the functions using them from the old installation.  A list of
problem libraries is in the file:
    loadable_libraries.txt

Failure, exiting

In File loadable_libraries.txt

Could not load library "$libdir/tds_fdw"

FEHLER:  konnte nicht auf Datei „$libdir/tds_fdw“ zugreifen: Datei oder Verzeichnis nicht gefunde

Go back to root-user and compile or install open dependencies

In my case

make clean && make && make install TDS_FDW Libs

Then go again to user postgres

su - postgres

and reexec pg_upgrade command

pg_upgrade -d /var/lib/pgsql/data93 -D /var/lib/pgsql/data -b /usr/lib/postgresql93/bin -B /usr/lib/postgresql94/bin

This output looks good:

If pg_upgrade fails after this point, you must re-initdb the

new cluster before continuing.

Performing Upgrade

...Later...

Setting next OID for new cluster                            ok

Sync data directory to disk                                 ok

Creating script to analyze new cluster                      ok

Creating script to delete old cluster                       ok

Upgrade Complete

----------------

Optimizer statistics are not transferred by pg_upgrade so,

once you start the new server, consider running:

    analyze_new_cluster.sh

Running this script will delete the old cluster's data files:

    delete_old_cluster.sh

Finishing :)

Start your PSQL with

systemctl start postgresql

and run as postgres

analyze_new_cluster.sh

it lies in /var/lib/pgsql folder

5 minutes or whatever your SATA controller can move :)
