  3.    The view <code class="structname">pg_file_settings</code> provides a summary of

  4.    the contents of the server's configuration file(s).  A row appears in

  5.    this view for each <span class="quote">“<span class="quote">name = value</span>”</span> entry appearing in the files,

  6.    with annotations indicating whether the value could be applied

  7.    successfully.  Additional row(s) may appear for problems not linked to

  8.    a <span class="quote">“<span class="quote">name = value</span>”</span> entry, such as syntax errors in the files.

  9.   </p><p>

  10.    This view is helpful for checking whether planned changes in the

  11.    configuration files will work, or for diagnosing a previous failure.

  12.    Note that this view reports on the <span class="emphasis"><em>current</em></span> contents of the

  13.    files, not on what was last applied by the server.  (The

  14.    <a class="link" href="view-pg-settings.html" title="51.86. pg_settings"><code class="structname">pg_settings</code></a>

  15.    view is usually sufficient to determine that.)

  16.   </p><p>

  17.    By default, the <code class="structname">pg_file_settings</code> view can be read

  18.    only by superusers.

  23.    If the configuration file contains syntax errors or invalid parameter

  24.    names, the server will not attempt to apply any settings from it, and

  25.    therefore all the <code class="structfield">applied</code> fields will read as false.

  26.    In such a case there will be one or more rows with

  27.    non-null <code class="structfield">error</code> fields indicating the

  28.    problem(s).  Otherwise, individual settings will be applied if possible.

  29.    If an individual setting cannot be applied (e.g., invalid value, or the

  30.    setting cannot be changed after server start) it will have an appropriate

  31.    message in the <code class="structfield">error</code> field.  Another way that

  32.    an entry might have <code class="structfield">applied</code> = false is that it is

  33.    overridden by a later entry for the same parameter name; this case is not

  34.    considered an error so nothing appears in

  35.    the <code class="structfield">error</code> field.

  38.    ways to change run-time parameters.
