Hi!
I've skimmed through the thread and checked the patchset. Everything looks good, except one paragraph, which doesn't look completely clear.
+ <para> + This emulates the functionality provided by + <xref linkend="sql-createtype"/> but sets the created object's + <glossterm linkend="glossary-type-definition">type definition</glossterm> + to domain. + </para>
As I get it states that CREATE DOMAIN somehow "emulates" CREATE TYPE. Could you please, rephrase it? It looks confusing to me yet.
v5 attached, looking at this fresh and with some comments to consider.
I ended up just combining both patches into one.
I did away with the glossary changes altogether, and the invention of the new term. I ended up limiting "type's type" to just domain usage but did a couple of a additional tweaks that tried to treat domains as not being actual types even though, at least in PostgreSQL, they are (at least as far as DROP TYPE is concerned - and since I don't have any understanding of the SQL Standard's decision to separate out create domain and create type I'll just stick to the implementation in front of me.
