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
