Hallo all,

in part VI (the reference), the online manual for 8.0.1 states for command
CREATE DOMAIN for parameter
CHECK (expression)
that currently
"...CHECK expressions cannot contain subqueries nor refer to
variables other than VALUE."

So, is this an item for the TODO list? I can't find it there. Or do I
overlook something?
This is also stated in the page about CREATE TABLE.

Best regards,
Wolfgang
