I want to upgrade from v9.0 to 9.1 (I use PostgreSQL for Windows) using a
backup of my actual DB and then restoring it to the new version. Reading
the documentation, see that it is recommended to perform a pg_dump with
version 9.1. I have both versions installed using ports 5432 and 5433, so
the 2 services are running. So, I change to folder "bin" of v9.1 and type
the pg_dump command but I get a message telling me that the database I am
trying to backup does not exist and this is obvious because such a DB was
created with v9.0. I will very much appreciate any advice.
Respectfully,
Jorge Maldonado
