Hallo! I made an debian update of postgresql, from 6.5.?? to 7.0.1. (?) ... That worked fine. I then created my database and access user again, started psql and created the database from the dump I have made some time ago. In fact, the database is created, all the table are there, empty, as I have saved them. Logged in as user ludwig I can insert data with no problem. But as my small Perl-program tries to connect to the database, that does not work. postgres.log: "Peer authentication failed for user 'ludwig'" What to do?
