The below fixes it for me... Its probably in the wrong place, and
does not even try to do any detection... but here it is anyway

*** a/src/backend/parser/analyze.c
--- b/src/backend/parser/analyze.c
***************
*** 538,543 **** transformInsertStmt(ParseState *pstate, InsertStmt *stmt)
--- 538,545 ----
*/
List *valuesLists = selectStmt->valuesLists;

+ pstate->p_hasSubLinks = true;
+
Assert(list_length(valuesLists) == 1);

/* Do basic expression transformation (same as a ROW() expr) */
