That's pretty interesting ... can you put together a self-contained test
case?  That might be a bit difficult because this is probably dependent
on data statistics.  But it should at least be possible to determine
which join clause is causing the problem, and then show us the pg_stats
entries for the columns used in the join.  This isn't going to be
dependent on whether the command is a DELETE or not, just the table join
conditions.
