Hmm,Data Define commands are unrecoverable in many DBMS-s. 
Is it necessary to allow PostgreSQL to execute Data Define
commands inside transactions ?
If so,is it possible ? 

For example,should the following be possible ?

[A table t exists.]

begin;
drop table t;
create table t (dt int4);
insert into t values (1);
drop table t;
abort;
