Manual:Text table/pl

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. 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
 * | Text is compressed with PHP's gzdeflate function. If the  option is on, new rows (=current revisions) will be gzipped transparently at save time. Previous revisions can also be compressed by using the script
 * | utf-8
 * | Text was stored as UTF-8. If the  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.
 * | 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. Zobacz też.
