Breaking: #77390 - Expected return type of hook getResultRows_SQLpointer in Indexed Search changed

See Issue #77390

Description

As part of migrating the core code to use Doctrine DBAL the expected return value of the hook getResultRows_SQLpointer in EXT:indexed_search has changed.

It is required that \Doctrine\DBAL\Driver\Statement objects are returned instead of the previous types bool or \mysqli_result.

Impact

3rd party extensions implementing the hook getResultRows_SQLpointer need to provide the correct return type, otherwise fatal errors will occur when processing the search results.

Affected Installations

Installations using 3rd party extensions that implement the hook getResultRows_SQLpointer for Indexed Search.

Migration

Migrate the implementation of the hook to provide the expected Doctrine Statement object.
