template. 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.

are not given, since the argument list for each type of function is
predetermined. The lexize function is required, but the init function
is optional.
