+Subject: [PATCH 06/10] [fts3] Disable fts3_tokenizer and fts4.
 
 fts3_tokenizer allows a SQLite user to specify a pointer to call as a
 function, which has obvious sercurity implications.  Disable fts4 until
 someone explicitly decides to own support for it.  Disable fts3tokenize
 virtual table until someone explicitly decides to own support for it.
 
 No original review URL because this was part of the initial Chromium commit.
