Not sure why you are seeing a crash instead of a complaint, but
there's no chance of making such a huge VIEW expression work in
6.5 --- the rule text won't fit in 8K.  Try it in 7.0.2 (which
has still got the 8K limit, but at least it compresses the text).

BTW I tend to agree with the other comment that this seems a clumsy
way to go about it.  I'd think about making a table containing a
pattern column and a browser-name column and doing the view as a
join.  Might be a little tricky to ensure you get only one match,
however ...
