Well the problem has been hidden, not solved. It did establish that
invoking parallel query has something to do with it. There also the fact
that by max_parallel_workers_per_gather is set to 0 by default. So the
setting you had previously(32) would imply that someone wanted to use
parallel query. If it is re-enabled then you are back to the error. To
help solve the problem for yourself and others could you supply relevant
information to the this problem report:
