Dear All. I am using ubuntu 11.04 to install psql 8.4 while following the steps on website: http://www.ros.org/wiki/sql_database/Tutorials/Installing%20a%20PostgreSQL%20Server I find two problem. The first one is: I use another user, not root, so I try to modify the file. and psql --username postgres works nice and I can also add the user CREATE ROLE willow LOGIN CREATEDB CREATEROLE PASSWORD 'willow'; I also enable tcp/ip connection # Anybody through TCP/IP with password host all all 0.0.0.0 0.0.0.0 md5

---

listen_addresses = '*'

---

Then I restart my computer. Try step 5.1

willow user can connect locally with password

local all willow md5

---

ps auxw | grep postgresql sudo kill -HUP xxxx

---

To check that it is working, try logging into psql on localhost as the new user:

psql --username willow --password --dbname postgres

---

Then I got the following error:

administrator@ubuntu:/etc/postgresql/8.4/main$ psql --username willow --password --dbname postgres Password for user willow:

psql: FATAL: Ident authentication failed for user "willow"

Do I need to change back the setting for "listen_addresses = '*'" as comment local host??

---

The second question is that when I run sudo apt-get install pgadmin3 and pgadmin3

I can not find the menu with

File -> Add Server...

etc only a plug in item is to add a connect to a server. Who can give a detail explanation on how to setup for local server to run PR2 SimpleGraspingDemo.
