Parallel safety restriction in 17

Hello,

I've stumbled upon this statement in parallel.sgml:

 > The following operations are always parallel restricted:
 > ...
 > Plan nodes to which an <literal>InitPlan</literal> is attached.

It looks like this is no longer true since e08d74ca, in which plan nodes 
with initPlans were allowed to be parallel-safe.

Thanks,
Egor
