That seems to do it. Thanks Mike! You are the best.
Sure looks simple, but I honestly wasn't even close. I'll definitely commit this concept to memory for next time.

What I am trying to do is write a single Postgres query/function which returns all of a user's work_ous and their ancestors without duplicates. I see that actor.org_unit_ancestors() is there, and selecting the work_ous is simple enough, but how can one combine them into a single result set? It seems relatively simple, but I just can't get it right.

How about:
select distinct (actor.org_unit_ancestors(work_ou)).id from
permission.usr_work_ou_map where usr = XXX;
