Moin, I have two database servers. One running postgresql 6.0 and the new one running 6.5.1. If I run "psql -h oldone -d oldone -u" from the newer server and input username and password psql says: Connection to database 'oldone' failed. Failed to authenticate client as Postgres user 'olduser' using authentication scheme 131072. What does it mean and how can I fix this. Many thanks Matthias ************
