I think one thing we could do minimize the chance of such an
error is set the value of parallel workers to be used for plan equal
to max_worker_processes if parallel_seqscan_degree is greater
than max_worker_processes. Even if we do this, still such an
error can come if user has registered bgworker before we could
start parallel plan execution.

Can we check the number of free bgworkers slots to set the max workers?
