Text search templates define the functions that implement + text search dictionaries. A template is not useful by itself, but must + be instantiated as a dictionary to be used. The dictionary typically + specifies parameters to be given to the template functions. + </p><p> + If a schema name is given then the text search template is created in the + specified schema. Otherwise it is created in the current schema. + </p><p> + You must be a superuser to use <code class="command">CREATE TEXT SEARCH + TEMPLATE</code>. This restriction is made because an erroneous text + search template definition could confuse or even crash the server. + The reason for separating templates from dictionaries is that a template + encapsulates the <span class="quote">“<span class="quote">unsafe</span>”</span> aspects of defining a dictionary. + The parameters that can be set when defining a dictionary are safe for + unprivileged users to set, and so creating a dictionary need not be a + privileged operation. + </p><p> + Refer to <a class="xref" href="textsearch.html" title="Chapter 12.
