-- Adds rev_text_id field to revision table.
|
|
-- This is a key to text.old_id, so that revisions can be stored
|
|
-- for non-save operations without duplicating text, and so that
|
|
-- a back-end storage system can provide its own numbering system
|
|
-- if necessary.
|

|
|
-- rev.rev_id and text.old_id are no longer assumed to be the same.
