Shouldn't CREATE TABLE LIKE copy the relhasoids property?

dst1 doesn't get an OID column:

regression=# create table src1 (f1 int) with oids;
CREATE TABLE
regression=# create table dst1 (like src1);
CREATE TABLE
regression=# \d+ src1
Table "public.src1"
Column | Type | Modifiers | Storage | Stats target | Description
--------+---------+-----------+---------+--------------+-------------
f1 | integer | | plain | |
Has OIDs: yes

regression=# \d+ dst1
Table "public.dst1"
Column | Type | Modifiers | Storage | Stats target | Description
--------+---------+-----------+---------+--------------+-------------
f1 | integer | | plain | |

If you don't find that problematic, how about this case?

regression=# create table src2 (f1 int, primary key(oid)) with oids;
CREATE TABLE
regression=# create table dst2 (like src2 including indexes);
ERROR: column "oid" named in key does not exist
