The assertion failure happens in an autovacuum worker.  So if you are
looking for a test that can be integrated in the tree, you could get
some inspiration from 006_signal_autovacuum.pl and rely on an
injection point wait with the existing autovacuum-worker-start.  My
2c, as it looks easy enough to avoid the hardcoded waits.
