CREATE TEXT SEARCH TEMPLATE — define a new text search template

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 dictionary 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
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 Chapter 12 for further information.
The name of the text search template to be created. The name can be schema-qualified.
The name of the init function for the template.
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.
There is no
CREATE TEXT SEARCH
TEMPLATE statement in the SQL standard.
