Postgres NOT in array
...indexes. If indexes are in mind:
SELECT COUNT(*) FROM "messages" WHERE 3 && recipient_ids
and the negative:
SELECT COUNT(*) FROM "messages" WHERE NOT (3 && recipient_ids)
An index can then be created like:

...ode like that.
For j<1000, j/1000 is zero (integer division). So:
(&main + (&exit - &main)*(j/1000))(j+1);
is equivalent to:
(&main + (&exit - &main)*0)(j+1);
Which is:
(&main)(j+1);
Which calls main with j+1.
If j == 1000, then the same lines comes out as...
