Also, aren't we too restrictive while requiring is_simple_values_sequence()?
For instance, I believe cases like this (containing Var) could be transformed too.
select * from t t1, lateral (select * from t t2 where t2.i in (values (t1.i), (1)));
I added it and attached a patch with diff file. To be honest, I didn't find queries except for var with volatile functions where the transform can't be applied.
I'm not sure about only cases where var can refer to something outside available_rels list but I couldn't come up with an example where that's possible, what do you think?
