Description
The spec has a section called F251, "Domain support".
From the SQL Spec: "A domain is a named user-defined object that can be specified as an alternative to a data type in certain places where a data type can be specified. A domain consists of a data type, possibly a default option, and zero or more (domain) constraints."
PostgreSQL implements this,
Perhaps it should be placed on wish list or the like
