Seems like the correct behavior to me. When CONSTRAINT is given, the
name is not optional AFAICS.
From SQL99:
<domain definition> ::=
CREATE DOMAIN <domain name> [ AS ] <data type>
[ <default clause> ]
[ <domain constraint>... ]
[ <collate clause> ]
<domain constraint> ::=
[ <constraint name definition> ]
<check constraint definition> [ <constraint characteristics> ]
<constraint name definition> ::=
CONSTRAINT <constraint name>
<check constraint definition> ::=
CHECK <left paren> <search condition> <right paren>
<constraint name> ::= <schema qualified name>
