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 <TT CLASS="COMMAND" >CREATE TEXT SEARCH TEMPLATE</TT >. 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" >"unsafe"</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 HREF="textsearch.html" >Chapter 12</A > for further information. </P ></DIV ><DIV CLASS="REFSECT1" ><A NAME="AEN71746" ></A ><H2 >Parameters</H2 ><P ></P ><DIV CLASS="VARIABLELIST" ><DL ><DT ><TT CLASS="REPLACEABLE" ><I >name</I ></TT ></DT ><DD ><P > The name of the text search template to be created.
