Why does a DDL command starts a transaction ?!

try
# set autommit=3Doff;
SET
# create table a (i int);
CREATE TABLE
# create table b (i int);
ERROR: current transaction is aborted, queries ignored until end of=20
transaction block
# commit;
COMMIT
# create table b (i int);
CREATE TABLE
# \d
List of relations
Schema | Name | Type | Owner
----------+---------------+-----------+-------
public | a | table | pgsql
public | b | sequence | pgsql

Dont you find curious a commiting of a DDL ?
