My $0.02 is that something that's type-specific belongs with the type,
not with clients.
As to the argument about displaying a check or an X, why should that
capability only exist for boolean types? For example, why not allow psql
to convert a numeric value into a bar of varying sizes? I've frequently
emulated that with something like SELECT repeat( '*', blah * 30 /
max_of_blah ). I'm sure there's other examples people could think of.
