Manual:Text table

The text table holds the wikitext of individual page revisions.

 may also store data here.

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

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.
