Manual:Text table

The text table holds the wikitext of individual page revisions.

If using Postgres or Oracle, this table is named pagecontent.

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

If you updated your wiki from MediaWiki 1.4 or older to a newer version, and if you have then run update.php at least once, you will still have old columns in the text table, whose contents have been migrated to the ' table and the ' table (content is copied, not cut).

These columns in the text table will not be used anymore.

All fields in the text table except old_id, old_text and old_flags are not needed anymore and can be safely deleted.

old_id
Unique integer used to identify each text.  in  table and  table.

<tvar|ar_text_id></> are keys to this column.

old_text
The wikitext of the page.

old_flags
Comma-separated list of flags.

Contains the following possible values:


 * {|class="wikitable"


 * | gzip</tt>
 * | Text is compressed with PHP's <tvar|gzdeflate>gzdeflate</tt></> function. If the <tvar|CompressRevisions></> option is on, new rows (=current revisions) will be gzipped transparently at save time.  Previous revisions can also be compressed by using the script <tvar|compressOld></>
 * | utf-8</tt>
 * | Text was stored as UTF-8. If the <tvar|LegacyEncoding></> option is on, rows without this flag will be converted to UTF-8 transparently at load time.
 * | object</tt>
 * | 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</tt>
 * | 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.  See also <tvar|DefaultExternalStore></>.
