Re: Migration from CentOS7 to RedHat 9

Yes, I used the same command I changed the values for this email. And that particular table with BLOBS took a longer time.

I am running a pg_restore now using -j 10 in the command. Please confirm, what you anticipate, will it take same time for restoration on Red Hat 9?

Thanks,
Wasim

Hi All

I took dump via pg_dump doing ssh from Red hat it took almost 10 hours for 400GB data including 99GB of BLOBS large objects.

ssh postgres@ipaddre "pg_dump -U postgres -d DB1 F c -b -v" > /path/pg.dump

I see a typo.  Is this a copy/paste of what you ran?

Is this normal?

Maybe.  Blobs are slow.  I'd have done a multi-threaded pg_dump, though blobs might be the bottleneck.
