For reasons of translation, you can't do something like "%s \"%s\"
does not exist, skipping". Instead I think you need an array that
works something like dropmsgstringarray[], but based on the OBJECT_*
constants rather than the RELKIND_* constants. IOW, it maps the
object type to the full error message, not just the name of the object
type.
