Peter Eisentraut a3906b44c5 Fix incorrect lack of Datum conversion in _int_matchsel()
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.
