If I create a domain from a composite, it will complain with a "ERROR:
cdt.instant_message is not a valid base type for a domain" error.
I can't create a trigger for a composite either (technically it's not
a table, but I was hoping it might be treated as one internally).
Is there any way to do this? Are there any plans to change or expand
this functionality in the future?

For now you have to put all checks in custom constructor functions.

I must not be looking in the right place... the only thing I can find that seems remotely related, is the page on input/output functions for custom types. And I was under the impression that only applies to non-composite custom types. Did I miss something?
Thanks,
