-- Based on version 3 schema found in the wild by error diagnostics.
-- The schema was failing to migrate because the current-version
-- tables were being created before the migration code was called,
-- resulting in the migration code attempting to add columns which
-- already existed (see http://crbug.com/273203 ).
--
-- Should be razed by the deprecation code.
BEGIN TRANSACTION;

-- [meta] is expected.
CREATE TABLE meta(key LONGVARCHAR NOT NULL UNIQUE PRIMARY KEY,value LONGVARCHAR);

INSERT INTO "meta" VALUES('last_compatible_version','3');

-- [thumbnails] is optional for v3, but was not seen in any diagnostic
-- results.

-- [favicons] was present in v3, but [icon_type] is a v4 column.

-- [icon_mapping] is a v4 table.  Some cases didn't have the indices,
-- possibly because the migration code didn't create indices (they
-- were created optimistically on next run).

-- contain this table.
