coding would ignore startup cost differences of less than 1% of the estimated total cost; which was OK for normal planning but highly not OK if a very small LIMIT was applied afterwards, so that startup cost becomes the name of the game. Instead, compare startup and total costs fuzzily but independently. This changes the plan selected for two queries in the regression tests; adjust expected-output files for resulting changes in row order. Per reports from Dawid Kuroczko and Sam Mason.
