This is no different from the problem of changing a column type in place.
It's still being worked on.

*2.* Its difficult to see all the constraint defs on a domain .
information_schema.domain_constriants does not have the
definations just the names are present.

You need to join domain_constraints and check_constraints.

Groups.google.com has indexes of the mailing lists so you can use that
to search. I do because archives is unusably slow.

you know. we should do something about that :)

Yes i realize so. But what could be in principle wrong to allow increasing
storage size only eg varchar(30) to varchar(100) not integer to
varchar(100)
etc. I remeber there was already a long thread of discussion on it.
