Committed with some pgindenting.

Ignored because I committed what I think is the same or a similar
patch earlier.  Please resubmit any remaining changes.

Shouldn't StorePartitionBound() be responsible for issuing its own
invalidations, as StorePartitionKey() already is?  Maybe you'd need to
pass "parent" as another argument, but that way you know you don't
have the same bug at some other place where the function is called.

I expect I'm missing something here, but why do we need to hoist
RelationGetPartitionQual() out of InitResultRelInfo() instead of just
having BeginCopy() pass true instead of false?

(Also needs a rebase due to the pgindent cleanup.)

Committed.  It might have been good to include a test case.
