Yes the postgis 3 version has PROJ="6.2.1"
while the postgis 2.3 version has PROJ="Rel. 4.9.2, 08 September 2015"
So quite possibly a change in proj 6.

I find this quite disconcerting. This will affect how locations provided by apps
using GPS will be stored in our database and we havent noticed this sort of
sized error in our locations.

I guess we can continue to use postgis 2.X to keep the behaviour we're
accustiomed to.
