The <code class="structname">pg_ts_dict</code> 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 <code class="structfield">dictinitoption</code>,
whose format and meaning vary depending on the template.
