Reading the change log one feature strikes me as very useful for machine learning projects: ST_QuantizeCoordinates With this you should be able to store coordinates with whatever precision they come with but get back queries that only care about the 'city level' or 'block level' and can be encoded with an exact number of bytes for a neural net.
