+This upstream patch (r1672295) is needed to fix a test failure when built
+against sqlite 3.8.9.  See:

+Optimize STMT_SELECT_EXTERNALS_DEFINED when using Sqlite 3.8.9, by
+adding two more rows to the sqlite_stat1 table.
+
+This fixes a test failure in wc-queries-test.c, but actual users most
+likely don't notice a difference as a tablescan on an EXTERNALS tables
+index is not that expensive, given that most working copies don't have
+many externals.
+
+* subversion/libsvn_wc/wc-metadata.sql
+  (STMT_INSTALL_SCHEMA_STATISTICS): Add two rows.
+
+* subversion/tests/libsvn_wc/wc-queries-test.c
+  (test_schema_statistics): Add a dummy externals row to allow
+    verifying schema.
