Hello, I´ve installed postgresql 9.1 on ubuntu 12.04 with pgpoolII-3.3.3 and pgPoolAdmin. I´m trying to make a test with pgbench-tools to measure the performance of postgresql. So I move to the directory where is pgbench-tools and configure the config file. I try to execute this order: sudo -u postgres ./runset After this it appears a message "Removing old pgbench tables" First error message (seems not to be important) is: ERROR: table "accounts does not exist" After this it appears a message: VACUUM creating new pgbench tables After this creating tables 10000 tuples done 20000 tuples done ... 100000 tuples done ... vacuum...done. Run set #1 of 2 with 2 clients scale=1 Running tests using: psql -h localhost -U postgres -p 5432 pgbench Storing results using: psql -h localhost -U postgres -p 5432 pgbench And after this it comes "the crash": ERROR: relation "branches" does not exist LINE 1: select count(*) for branches ERROR: Attempt to determine database scale returned "", aborting it´s maybe and stupid issue and I´m not being able to solve it as i don´t have a high level of knowledge on those systems. Any idea about what to try? -- View this message in context: http://postgresql.nabble.com/trying-to-run-pgbench-tools-postgresql-ubuntu-ERROR-relation-branches-does-not-exist-tp5832477.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
