+
+ <para>
+ <command>CREATE TEXT SEARCH TEMPLATE</command> creates a new text search
+ 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.
+ </para>
+
+ <para>
+ 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.
+ </para>
+
+ <para>
+ You must be a superuser to use <command>CREATE TEXT SEARCH
+ TEMPLATE</command>. 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 <quote>unsafe</quote> 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.
