The point is that if WINDOW was not a reserved word in 8.3 but is in
8.4, then every reference to a user column of WINDOW in any 8.4
application will need to be double-quoted, and odds are the user did not
do that in 8.3.
I think users would rather have the restore fail, and know right away
they have an issue, than to do the upgrade, and find out later that some
of their application queries fail and they need to run around fixing
them. (FYI, pg_upgrade would use the new pg_dump and would not fail.)
In a way, the fact that the restore fails can be seen as a feature ---
they get the error before the go live on 8.4. (Yeah, I am serious.)
