Hello, I tried to delete all binary_upgrade schematas using this: $ psql -tc "SELECT datname FROM pg_database" -U postgres -p 5433 | xargs -I {} psql -d {} -U postgres -p 5433 -tc "drop schema if exists binary_upgrade cascade;" But got this: output is not a tty So I got the dblist from pgadmin and saved to file: That worked: $ cat dblist.txt | xargs -I {} psql -d {} -U postgres -p 5433 -tc "drop schema if exists binary_upgrade cascade;" pg_upgrade succeeded with the step: Checking for presence of required libraries ok But then I got: Checking database user is the install user Only the install user can be defined in the new cluster. Failure, exiting But this is the next story ;-) I can assure that deleting the schematas from the source db solves my initial problem.
