+Subject: [PATCH] sql: make VirtualCursor standard layout type
+
+sql::recover::VirtualCursor needs to be a standard layout type, but
+has members of type std::unique_ptr. However, std::unique_ptr is not
+guaranteed to be standard layout. Compiling with clang combined with
+gcc-11 libstdc++ fails because of this. Replace std::unique_ptr with
+raw pointers.
