It's hard to tell, because you aren't comparing apples to apples.
Try a prepared statement, like
prepare foo(int) as
SELECT
COUNT(*)::int4
FROM
_v1
WHERE
service_id = $1
;
execute foo(504);
which should produce results similar to the function. You could
then use "explain analyze execute" to probe further into what's
happening.
