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 tem-
       plates 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 dic-
       tionary 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 parame-
       ters  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 lex-
       ize 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.
