I think it has been shown enough times that the performance drop caused

way to carry out only the parse phase, and postpone planning until the
parameters have been received.
It's already done in 8.3 for unnamed plans, isn't it?
forgive my ignorance here, but if it's unnamed how can you reference it
later to take advantage of the parsing?
I may just be not understanding the terms being used here.
