That doesn't help in this case as the returned set will typically be

In that case you'd be wasting your time to get it to use an index
for the condition anyway.  Maybe you need to take a step back and
look at the query as a whole rather than focus on this particular
condition.

The query, sans this condition, is extremely fast and contains a LOT of other conditions (none of which cause trouble.)

It is only attempting to filter the returned tuples on the permission bit(s) involved that cause trouble.
