Hi, I know this is an old thread, but I wanted to chime in since I am having problems with this as well. I too am trying to run dbt5 against Postgres. Specifically I am trying to run it against Postgres 9.1beta3. After jumping through many hoops I ultimately was able to build dbt5 on my debian environment, but when I attempt to run the benchmark with: dbt5-run-workload -a pgsql -c 5000 -t 5000 -d 60 -u 1 -i ~/dbt5-0.1.0/egen -f 500 -w 300 -n dbt5 -p 5432 -o /tmp/results it runs to completion but all of the dbt5 log files contain errors like: terminate called after throwing an instance of 'pqxx::broken_connection' what(): could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"? I'm lead to believe that this is an error I would receive if the Postgres db were not running, but it is. In fact, the way dbt5-run-workload works it starts the database automatically. I have also confirmed it is running by manually connecting while this benchmark is in progress (and after it has already started the database and logged the above error). Any thoughts on why I might be getting this error? -- View this message in context: http://postgresql.1045698.n5.nabble.com/DBT-5-Postgres-9-0-3-tp4297670p4708692.html Sent from the PostgreSQL - performance mailing list archive at Nabble.com. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
