[forum:/forumpost/e61252062c9d286d|forum post e61252062c9d286d]. This fix
is more restrictive than necessary. It could be relaxed if the subquery does
not involve the table that is the subject of the DELETE.

the optimization of check-in [41c27bc0ff1d3135], always insert the
TK_IF_NULL_ROW expression nodes, even for TK_COLUMN expressions, as
