Authentication failures and related problems generally
manifest themselves through error messages like the following:
</p><p>
</p><pre class="programlisting">
FATAL: no pg_hba.conf entry for host "123.123.123.123", user "andym", database "testdb"
</pre><p>
This is what you are most likely to get if you succeed in contacting
the server, but it does not want to talk to you. As the message
suggests, the server refused the connection request because it found
no matching entry in its <code class="filename">pg_hba.conf</code>
configuration file.
</p><p>
</p><pre class="programlisting">
FATAL: password authentication failed for user "andym"
</pre><p>
Messages like this indicate that you contacted the server, and it is
willing to talk to you, but not until you pass the authorization
method specified in the <code class="filename">pg_hba.conf</code> file. Check
the password you are providing, or check your Kerberos or ident
software if the complaint mentions one of those authentication
types.
</p><p>
</p><pre class="programlisting">
FATAL: user "andym" does not exist
</pre><p>
The indicated database user name was not found.
</p><p>
</p><pre class="programlisting">
FATAL: database "testdb" does not exist
</pre><p>
The database you are trying to connect to does not exist. Note that
if you do not specify a database name, it defaults to the database
user name, which might or might not be the right thing.
</p><div class="tip"><h3 class="title">Tip</h3><p>
The server log might contain more information about an
authentication failure than is reported to the client. If you are
confused about the reason for a failure, check the server log.
