Manual:Text table

The text table holds the wikitext of individual page revisions. If using Postgres, this table is named pagecontent.

Field names are a holdover from the 'old' revisions table in MediaWiki 1.4 and earlier.

old_flags: -- gzip: text is compressed with PHP's gzdeflate function. -- utf8: 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. -- 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.
