I'm now thinking of setting up a dedicated AWS EC2 instance just for these little DBs that get created by our automated tests. If the problem happens there as well then that would strongly point towards a bug in PostgreSQL, wouldn't it?
Many other people besides you would have noticed regular corruption of system catalogs.
Meanwhile, what do I do with the existing server, though? Just try to drop the problematic DBs again manually?
"Fix the hardware" is what you do.
