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\&. .PP 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\&. .PP You must be a superuser to use \fBCREATE TEXT SEARCH TEMPLATE\fR\&. 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 \(lqunsafe\(rq 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\&. .PP Refer to Chapter 12, Full Text Search, in the documentation for further information\&. .SH "PARAMETERS" .PP \fIname\fR .RS 4 The name of the text search template to be created\&. The name can be schema\-qualified\&. .RE .PP \fIinit_function\fR .RS 4 The name of the init function for the template\&. .RE .PP \fIlexize_function\fR .RS 4 The name of the lexize function for the template\&. .RE .PP The function names can be schema\-qualified if necessary\&. Argument types 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\&. .PP The arguments can appear in any order, not only the one shown above\&. .SH "COMPATIBILITY" .PP There is no \fBCREATE TEXT SEARCH TEMPLATE\fR statement in the SQL standard\&. .SH "SEE ALSO" ALTER TEXT SEARCH TEMPLATE (\fBALTER_TEXT_SEARCH_TEMPLATE\fR(7)), DROP TEXT SEARCH TEMPLATE (\fBDROP_TEXT_SEARCH_TEMPLATE\fR(7))
