Hello PostgreSQL experts,
I am trying to upgrade an instance of PostgreSQL in unix from 11.5 to 12.1.
I got the following error on upgrade verification step.
Is this not allowed?
UNIX:> pg_upgrade -d /hostname/pg/dpoc/data -D /hostname/pg/dpoc/data -b /hostname/pg/PostgreSQL-11.5/bin -B /hostname/pg/PostgreSQL-12.1/bin -p 5432 -P 9432 -c –v
