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

Of course, these days you have the option of just using pg_upgrade
against the original or a deep copy of the data directory.
