Bug Fix (user-visible misbehavior in an official stable release)

• Backported in #67931: Fixing the Not-ready Set error after the PREWHERE optimization for StorageMerge. #65057 (Nikolai Kochetov).
• Backported in #68062: Fix boolean literals in query sent to external database (for engines like PostgreSQL). #66282 (vdimir).
