I have an application where I am building a plan with SPI_plan and then this plan is called multiple times. There is one free parameter ($1) to the plan. The issue is with the order of the values returned. If $1 is identical during successive calls to SPI_execute_plan, is there any guarantee that the rows will be returned in the same order? I know that repeated queries can return rows in different order, but am specifically wondering about a prepared plan. (I can imagine the plan somehow snap-shots the table when prepared such that rows always come back in the same order, but I'm guessing that is not the case.) If not, I simply have to add an order by clause which will incur some overhead.
