NAME
       CREATE TEXT SEARCH TEMPLATE - define a new text search template


SYNOPSIS
       CREATE TEXT SEARCH TEMPLATE name (
           [ INIT = init_function , ]
           LEXIZE = lexize_function
       )


DESCRIPTION
       CREATE TEXT SEARCH TEMPLATE 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  dictio-
       nary to be used. The dictionary typically specifies parameters to be given to the template functions.

       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.

       You must be a superuser to use CREATE TEXT SEARCH TEMPLATE. 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 ''unsafe'' 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.

       Refer to in the documentation for further information.

PARAMETERS
       name   The name of the text search template to be created. The name can be schema-qualified.

       init_function
              The name of the init function for the template.

       lexize_function
              The name of the lexize function for the template.

       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.


       The arguments can appear in any order, not only the one shown above.


COMPATIBILITY
       There is no CREATE TEXT SEARCH TEMPLATE statement in the SQL standard.
