Your proposal is

	Waiting for the group leader process to clear the transaction ID of
	this backend at the end of a transaction.

	Waiting for the group leader process to update the transaction status
	for this backend.

Mine is

	Waiting for the group leader to clear the transaction ID at transaction
	end.

	Waiting for the group leader to update transaction status at
	transaction end.

IMHO the latter doesn't convey substantially less information, and it fits
a little better with the terse style of the other wait events nearby.  But
I'll yield to majority opinion here.
