I am trying to upgrade from PostgreSQL 9.0.22 to 9.4.4. When I attempt to execute pg_upgrade, I get the following error: *Performing Consistency Checks* *-----------------------------* *Checking cluster versions* *This utility can only upgrade to PostgreSQL version 9.4. * The command I am executing is: /app/PostgreSQL/9.4/bin/pg_upgrade -b /app/PostgreSQL/9.0/bin -B /app/PostgreSQL/9.4/bin -c -d /pgsql/stip/data9 -D /pgsql/stip/data94 The data directory for 9.4 is a copy of the data directory for 9.0. I am able to login to the 9.0 data via the 9.0 server and client, so I cannot see how pg_upgrade thinks the data is at a 9.4 level.
Well there's your problem:) The the new(9.4) data directory needs to have been created by 9.4. Right now pg_upgrade thinks it is doing a 9.0 to 9.0 upgrade. The error message is not telling you it is at 9.4 but at a Postgres other then 9.4.
Use the 9.4 initdb or pg_ctl init to create a new data directory that pg_upgrade can move the 9.0 data to.
The error message is not of much help. I have tried searching for an article or document that addresses this particular error message to no avail. Any help you can provide would be greatly appreciated.
