   Information about text search configuration objects can be obtained
   in <span class="application">psql</span> using a set of commands:
</p><pre class="synopsis">
\dF{d,p,t}[<span class="optional">+</span>] [<span class="optional">PATTERN</span>]
</pre><p>
   An optional <code class="literal">+</code> produces more details.
  </p><p>
   The optional parameter <em class="replaceable"><code>PATTERN</code></em> can be the name of
   a text search object, optionally schema-qualified.  If
   <em class="replaceable"><code>PATTERN</code></em> is omitted then information about all
   visible objects will be displayed.  <em class="replaceable"><code>PATTERN</code></em> can be a
   regular expression and can provide <span class="emphasis"><em>separate</em></span> patterns
   for the schema and object names.  The following examples illustrate this:
