Log Message:
-----------
Allow USING and INTO clauses of plpgsql's EXECUTE to appear in either order.

Aside from being more forgiving, this prevents a rather surprising misbehavior
when the "wrong" order was used: the old code didn't throw a syntax error,
but absorbed the INTO clause into the last USING expression, which then did
strange things downstream.

Intentionally not changing the documentation; we'll continue to advertise
only the "standard" clause order.

Backpatch to 8.4, where the USING clause was added to EXECUTE.
