I think so. IIUC, the idea is that after parsing we find out whether
the given name is table, sequence, or any other object. Here, I think
the name could be either of table or sequence because, for schema, we
won't be knowing whether to include tables, sequences, or both in the
schema. Also, we can have the same name for schema and table so it
might be tricky to distinguish among those unless we give priority to
one of those.
