The code used
return (Selectivity) 0.0;
where
PG_RETURN_FLOAT8(0.0);
would be correct.
On 64-bit systems, these are pretty much equivalent, but on 32-bit
systems, PG_RETURN_FLOAT8() correctly produces a pointer, but the old
wrong code would return a null pointer, possibly leading to a crash
elsewhere.
We think this code is actually not reachable because bqarr_in won't
accept an empty query, and there is no other function that will
create query_int values. But better be safe and not let such
incorrect code lie around.
