Hello, I am trying to upgrade my PG instance from 10.7 to 11.5.
I got an error in doing so. Any idea what I am missing? Example: pg_upgrade -d /hostname/pg/dpoc/data -D /hostname/pg/dpoc115/data -b /hostname/pg/PostgreSQL-10.7/bin -B /hostname/pg/PostgreSQL-11.5/bin -p 5432 -P 9432 -c -v Error message: old and new pg_controldata WAL segment sizes are invalid or do not match Failure, exiting ________________________________ IMPORTANT: The information contained in this email and/or its attachments is confidential.
