pg_ts_template
   The pg_ts_template catalog contains entries
   defining text search templates.  A template is the implementation
   skeleton for a class of text search dictionaries.
   Since a template must be implemented by C-language-level functions,
   creation of new templates is restricted to database superusers.
  
PostgreSQL's text search features are described at length in Chapter 12.
