Hi.
The description of DEFAULT in the documentation currently says:
"The value is any variable-free expression (subqueries and
cross-references to other columns in the current table are not allowed)."
But the value cannot be an aggregate expression, a window function, or a
set-returning function either, so maybe we should list these items too?
Attached is a patch that fixes the text in two places where the above
description appears.
Thanks,
Amit
