As mentioned previously [1], I think there is a value to allow
appending the options not given in the original statement (say
tablespace) but it would be better to provide additional information
with some subscription option like expanded_mode  = on/off. With
expanded_mode = off, we should only WAL log the information required
to construct the original DDL statement.

I think we can now remove ObjTree part of the code as we have seen
that we can form the required jsonb without it as well.
