I am seeing the following error message repeatedly on all pages after switching up to PHP 8.5.1 from PHP 8.3.26 ...

Deprecated function: Constant PDO::MYSQL_ATTR_USE_BUFFERED_QUERY is deprecated since 8.5, use Pdo\Mysql::ATTR_USE_BUFFERED_QUERY instead in Drupal\mysql\Driver\Database\mysql\Connection::open() (line 140 of core\modules\mysql\src\Driver\Database\mysql\Connection.php).

Related issues: +#3543710: Address PHP 8.5 deprecations of driver specific PDO constants and methods

What is the precise Drupal version? Drupal 11 removed this deprecation six months ago.

Ah, my mistake, this is on my remaining Drupal 10 site - it's 10.6.3 to be precise and my local database is MySQL 8.4.3.

Drupal 10.6 on PHP 8.5

will probably work, but deprecation notices will be generated and bug reports will not be accepted

If production sites are showing deprecation warnings, their error display settings are incorrect. Otherwise, to remove them on dev sites, upgrade to Drupal 11 or use PHP 8.4.
