Hey,
So this came across my twitter feed:

I have verified the oddness with a newer version:
psql -U postgres
psql (9.5.3)
Type "help" for help.
postgres=# create domain text char(3);
CREATE DOMAIN
postgres=# create domain text char(2);
ERROR: type "text" already exists
postgres=# \dD List of domains Schema | Name | Type | Modifier | Check
--------+------+------+----------+-------
(0 rows)
postgres=# create domain textd char(2);
CREATE DOMAIN
postgres=# \dD List of domains Schema | Name | Type | Modifier | Check
--------+-------+--------------+----------+------- public | textd | character(2) | |
(1 row)
