-- gzip: text is compressed with PHP's gzdeflate() function.
-- utf-8: text was stored as UTF-8.
-- If $wgLegacyEncoding option is on, rows *without* this flag
-- will be converted to UTF-8 transparently at load time. Note
-- that due to a bug in a maintenance script, this flag may
-- have been stored as 'utf8' in some cases (T18841).
-- object: text field contained a serialized PHP object.
-- The object either contains multiple versions compressed
-- together to achieve a better compression ratio, or it refers
-- to another row where the text can be found.
-- external: text was stored in an external location specified by old_text.
-- Any additional flags apply to the data stored at that URL, not
-- the URL itself. The 'object' flag is *not* set for URLs of the
-- form 'DB://cluster/id/itemid', because the external storage
-- system itself decompresses these.
