Dumping views as views?

In a continuing effort to make pg_dump produce valid SQL where possible, I
would like to move away from the 'Create Table'/'Create Rule' method of
defining views, and actually dump the 'Create View' command.

This seems quite do-able, but before I start I thought I would ask if there
were any reasons people could think of for not doing this?

The approach will be:

- when getting table info, also call pg_get_viewdef (which returns 'not a
view' for non-view relations).

- When dumping rules, ignore all 'view rules'.

- Dump the 'Create View' statement in oid order as per normal.

It would be really nice if there was a simple way of detecting view rules
that was analagous to relkind. Is there a reason why this has not been
done? Has it been done?

Maybe the code that checks the rule name to see if it is a view could be
put in the backend?
