If you want to make your life difficult, that's ok. Remember that this change would only be for *local* connections for the duration of the upgrade. As an alternative, you could create a password file or, if that is also too insecure, set the PGSSLCERT and PGSSLKEY environment variables so that you can use a client certificate to connect. Other authentication methods might also be possible; you'll have to experiment. Yours, Laurenz Albe -- Cybertec | https://www.cybertec-postgresql.com
