On Microsoft Windows the file is named + <code class="filename">%APPDATA%\postgresql\pgpass.conf</code> (where + <code class="filename">%APPDATA%</code> refers to the Application Data subdirectory in + the user's profile). + Alternatively, the password file to use can be specified + using the connection parameter <a class="xref" href="libpq-connect.html#LIBPQ-CONNECT-PASSFILE">passfile</a> + or the environment variable <code class="envar">PGPASSFILE</code>. + </p><p> + This file should contain lines of the following format: +</p><pre class="synopsis"> +<em class="replaceable"><code>hostname</code></em>:<em class="replaceable"><code>port</code></em>:<em class="replaceable"><code>database</code></em>:<em class="replaceable"><code>username</code></em>:<em class="replaceable"><code>password</code></em> +</pre><p> + (You can add a reminder comment to the file by copying the line above and + preceding it with <code class="literal">#</code>.) + Each of the first four fields can be a literal value, or + <code class="literal">*</code>, which matches anything. The password field from + the first line that matches the current connection parameters will be + used. (Therefore, put more-specific entries first when you are using + wildcards.) If an entry needs to contain <code class="literal">:</code> or + <code class="literal">\</code>, escape this character with <code class="literal">\</code>. + The host name field is matched to the <code class="literal">host</code> connection + parameter if that is specified, otherwise to + the <code class="literal">hostaddr</code> parameter if that is specified; if neither + are given then the host name <code class="literal">localhost</code> is searched for. + The host name <code class="literal">localhost</code> is also searched for when + the connection is a Unix-domain socket connection and + the <code class="literal">host</code> parameter + matches <span class="application">libpq</span>'s default socket directory path. + In a standby server, a database field of <code class="literal">replication</code> + matches streaming replication connections made to the primary server. + The database field is of limited usefulness otherwise, because users have + the same password for all databases in the same cluster. + </p><p> + On Unix systems, the permissions on a password file must + disallow any access to world or group; achieve this by a command such as + <code class="command">chmod 0600 ~/.pgpass</code>. If the permissions are less + strict than this, the file will be ignored. On Microsoft Windows, it + is assumed that the file is stored in a directory that is secure, so + no special permissions check is made. + </p></div><div class="navfooter"><hr /><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="libpq-envars.html" title="34.15.
