Re: Dumping data using pg_dump after chrooting to a different partition

Hi Kevin,

Can you please elaborate how to do the following?

connecting through a TCP connection and piping directly
from pg_dump to psql

Since we could have DB schema changes between the versions, we may not
be able to copy the data directory.

Does pg_upgrade support changes to the schema?

Thanks.

Radha
