Yeah, it's supposed to do that. Note that the second call to
CollationCreate() in pg_import_system_collations() has the "if not
exists" argument true regardless. So the error appears to come from the
first one.
What's fishy about this is that I can't reproduce it locally in a
variety of VMs, and the buildfarm is not unanimous either.
