I’m introducing support for parsing UUIDs from PostgreSQL in LibPQ.jl and I would like to know if anyone would be negatively impacted by setting UUID as the default type for the PostgreSQL uuid type. This means that if you select a uuid from PostgreSQL you might get a Julia UUID where you previously got a String.
In general, how do you feel about LibPQ.jl minor versions adding types such that what used to default to String now defaults to a specific Julia type? In this case UUID is built into Base and exported by the UUIDs stdlib, but does your answer change if LibPQ.jl returns a type from a particular package?
There are also some cases like Decimal where I think everyone would be happy if we switched to a different numeric type, but I’m not sure whether people would want a major version bump for something like that.
