-Subject: [PATCH 10/23] [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.
-
-No original review URL because this was part of the initial Chromium commit.
