third_party/sqlite/fts3_85522.patch

   1 Fix http://crbug.com/85522
   2
   3 WebDatabase uses an authorizer to prevent inappropriate access.
   4 fts3.c uses 'PRAGMA page_size' to tune the query optimizer, but PRAGMA
   5 is on the disallowed list.  This patch adds a default return value for
   6 SQLITE_AUTH failures.
