It still happens nowadays when you upgrade from FreeBSD 10.x to 11.x or
from 11.x to 12.x. 

It doesn't happens deterministically but after upgrading the machines I
often find myself with PKG unable to upgrade some programs because it
cannot delete/add users. 

The fix is, as already said, pwd_mkdb (-p)
