An edge case I came across the other day was a unique index on a large
string: postgresql popped up and told me that I couldn't insert a
value into the field because the BTREE-index-based constraint wouldn't
support the size of string, and that I should use a HASH index
instead. Which, of course, I can't, because it's fairly clearly
deprecated in the documentation...
