If someone fixes this can we make sure it goes into 7.4.4 as well (if 
it's not a drastic code change)?

It's not a data corrupting bug but it's stopping view definitions from 
"working as advertised" which is bad if you're used to being able to 
rely on them.  :-/

For now, I'll personally use the pg_dump version of the query, or maybe 
see if the one in backend/catalog/information_schema.sql can be run 
directly.  :)
