pg_ts_dict
   The pg_ts_dict catalog contains entries
   defining text search dictionaries.  A dictionary depends on a text
   search template, which specifies all the implementation functions
   needed; the dictionary itself provides values for the user-settable
   parameters supported by the template.  This division of labor allows
   dictionaries to be created by unprivileged users.  The parameters
   are specified by a text string dictinitoption,
   whose format and meaning vary depending on the template.
  
PostgreSQL's text search features are described at length in Chapter 12.
