Re: Question about pg_upgrade from 9.2 to X.X

Awesome, thanks Sergei and Justin,

Finally, I am able to upgrade the DB from 9.2 to 9.6 successfully after
dropping Schema (reorg) without library issue.
Also , I have installed -Contrib. package for Version:10 and upgraded to
version 10.7 too.

On both the cases , I have used --link option and it took just fraction of
seconds ( I feel 'Zero' Downtime effect )

Any pointers for pg_repack schema creation ?
Will there be any impact in the future , Since i used --link option ?

Regards,
Raju
