pg_ts_config
   The pg_ts_config catalog contains entries
   representing text search configurations.  A configuration specifies
   a particular text search parser and a list of dictionaries to use
   for each of the parser's output token types.  The parser is shown
   in the pg_ts_config entry, but the
   token-to-dictionary mapping is defined by subsidiary entries in pg_ts_config_map.
  
PostgreSQL's text search features are described at length in Chapter 12.
