I have used pgadmin III to do that so you may want to try it.

TIP 6: Have you searched our list archives?
http://archives.postgresql.org
Check the pg_hba.conf file to see if you have access to the database, as user that you are trying to connect as, from the IP you are trying to connect from. I'll bet that you don't. Check you postgres error logs, and you should see the refused connection. You might have to tweak the logging settings. Also, the exact error you get would be a bit more helpful.

Hello, > Iam trying to take a dump of my DB from one machine to another in this > fashion: > > on the secondary database: > > pg_dump -b -h 172.16.1.20 (dbname) > /tmp/dump.dump Can you get connect with psql -h 172.16.1.20 (dbname) I think, you /etc/pg_hba.conf must be configured to grant this access. And don't forget to reload the postmaster after this. Look in the log of postgresql. Bye Thomas
Hello, > Yes I can get connected by psql -h 172.16.30.2 (dbname) and I can also connect to the remote DB using phpPgAdmin. I have given the permissions on pg_hba.conf file. Hmmm, when you connected with psql -h 172.16.30.2 (dbname), are you able to get data with the select-command? If not, you must grant access with the grant-command. And you should look to the logfile of postgresql. Bye Thomas
