"blah" is not a domain error

I know domain support is pretty broken, so maybe this is a known issue...

decibel=# create table test(m money);
CREATE TABLE
decibel=# insert into test values('-1.00');
INSERT 0 1
decibel=# alter domain money add check(money>0);
ERROR: "money" is not a domain
decibel=# drop domain money;

What are you concerned about exactly? It looks perfectly reasonable
to me. "money" is a base type not a domain.

Oops... I thought we'd removed it.

Shouldn't it be an error to create a domain that conflicts with an existing
type?

bench=# create domain money as numeric(21,2);
CREATE DOMAIN
bench=# drop domain money;
ERROR: "money" is not a domain
bench=# create domain money as numeric(21,2);
ERROR: type "money" already exists
bench=# select version();

It is, if you create it in the same schema. "money", along with all the
other built-in types, is in pg_catalog not public.
