how can has_table_privilege() "lie" like this?

It doesn't lie. The role has DELETE privilege. I guess what it lacks is
the SELECT privilege. If you do a "DELETE FROM ... WHERE ...", you need
the SELECT privilege to perform the WHERE. Without "WHERE ...", it would
work without the SELECT privilege.

Right on the money! Merci Guillaume!!! --DD

PQ: NOTICE: can DELETE = t
PQ: NOTICE: can SELECT = f

So the below from the original post was not correct:

"My setup ensures that the role I SET LOCAL ROLE to, has (indirectly)
been granted DMLs on that table."
