The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/10/upgrading.html Description:
https://www.postgresql.org/docs/10/upgrading.html It would be helpful to make a note for Linux users that you have login interactively as the postgres user ie. "sudo -u postgres -i" before running such commands as "pg_dumpall -p 5432 | psql -d postgres -p 5433". Otherwise you'll receive the template1 error about the user. Thanks.
