Exactly as Ramsey said - although if your database IS in fact on a remote machine, you would not want "trust", since that would imply anybody could
connect as anybody to any database.
If your database is "mybase" and your database user is "myuser" and your development machine is 192.168.0.100, then your line ought to be something like:
host mybase myuser 192.168.0.100/32 md5
Only use a trust relationship if the server doesn't allow user logins or the users logging in are truly trusted, and then only for 127.0.0.1/8 :)
- however
If your database happens to be on your _local_ machine (same as your development/deployment) - like the Postgres.app for Mac OS X, then something else is amuck.
One thing that comes to mind - does your database actually exist?
psql -l
lists the databases
IF the database you expect to use doesn't exist, of course there will be no connection - so, if the database doesn't exist, I'll presume that the user doesn't exist either. In that case, you'll need to create both.
As the user running the postgres database (logged-in user if "Postgres.app" or "postgres","psql" or other db-centric user of the OS the DB is running on:
$ psql
# create user myuser password 'reallySecret2013';
...
# create database myuser owner myuser encoding='UTF8';
...
# exit
Then try connecting again.
Hope this helps :)

Is the db on the same machine as the app? If not, this won’t work. You need to add the IP of your app server. Something like...
host all all 192.168.0.100 trust

Thanks for the reply. Here is my config in pg_hba.conf. It seems like this should not be causing the issue. Any other thoughts or something I am missing in this config?
Thanks,
Joe
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32<http://127.0.0.1/32> trust
# IPv6 local connections:
host all all ::1/128 trust

Have you given the user permission to connect to the database ?
Take a look at pg_hba.conf. Add a line for the user. If you _want_ the user to use a password, then the last column should be "password" or better yet "md5". If you want a trust-level connection, set it to "trust".

I went through all the steps to get WebObjects/Wonder installed and I can run HelloWorld. The problem appears to be with my Postgresql JDBC connection. I am running Postgres93.app. I added the postgresql-9.3-1100.jdbc3.jar to my project's Resources folder and added that jar to the build path. When I run and try to bootstrap my database, I cannot connect and I get the following error. Is there something that I missed in the setup process? Any help would be appreciated.
