The view <code class="structname">pg_file_settings</code> provides a summary of
the contents of the server's configuration file(s). A row appears in
this view for each <span class="quote">“<span class="quote">name = value</span>”</span> entry appearing in the files,
with annotations indicating whether the value could be applied
successfully. Additional row(s) may appear for problems not linked to
a <span class="quote">“<span class="quote">name = value</span>”</span> entry, such as syntax errors in the files.
</p><p>
This view is helpful for checking whether planned changes in the
configuration files will work, or for diagnosing a previous failure.
Note that this view reports on the <span class="emphasis"><em>current</em></span> contents of the
files, not on what was last applied by the server. (The
<a class="link" href="view-pg-settings.html" title="54.24. pg_settings"><code class="structname">pg_settings</code></a>
view is usually sufficient to determine that.)
</p><p>
By default, the <code class="structname">pg_file_settings</code> view can be read
only by superusers.

If the configuration file contains syntax errors or invalid parameter
names, the server will not attempt to apply any settings from it, and
therefore all the <code class="structfield">applied</code> fields will read as false.
In such a case there will be one or more rows with
non-null <code class="structfield">error</code> fields indicating the
problem(s). Otherwise, individual settings will be applied if possible.
If an individual setting cannot be applied (e.g., invalid value, or the
setting cannot be changed after server start) it will have an appropriate
message in the <code class="structfield">error</code> field. Another way that
an entry might have <code class="structfield">applied</code> = false is that it is
overridden by a later entry for the same parameter name; this case is not
considered an error so nothing appears in
the <code class="structfield">error</code> field.

ways to change run-time parameters.
