The short answer here is that 0.00603::double precision and
0.00603::real are unlikely to be exactly the same value, and
which one is greater is a matter of which direction the real
got rounded off in. On my machine the former is a bit larger:
regression=# select 0.00603::double precision - 0.00603::real;
?column?

but on another platform it could be the other way around.
