PostgreSQL has 60+ types and many look like eachother. How do you propose to differentiate?

Data Types are basically about value ranges (how many bits do you
need to hold the value) and formatting.
That is exactly wrong, at least in the PostgreSQL approach to the type
system. Data types are about functions and operators associated with
them. So it is not about what the data looks like, but what kind of
processing you want to do with it. Guessing that information from a
dump of data seems pretty much impossible.
