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.
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.
Thank you,
