When an `UPDATE` statement modifies a table's `INTEGER PRIMARY KEY`
(which acts as a `rowid` alias) alongside other indexed columns, the
index entries were incorrectly retaining the old `rowid`. This led to
stale index references, causing subsequent queries to return incorrect
results.
This change ensures that when the `rowid` alias is part of the `SET`
clause in an `UPDATE` statement, the new `rowid` value is used for
generating and updating index records. This guarantees that all index
entries correctly point to the updated row, resolving the data
inconsistency.
