EPSG:32630 is a better projected reference, since it shares the same
spheroid, WGS 84, as EPSG:4326 (rather than mixing in the older

degrees and you numbers are in degrees squared. If you want the number
in meters or feet then project then into an appropriate UTM or equal

I've got some building outlines that I'm pretty sure I've worked with

ST_Area returns extremely small numbers for any of the buildings.
It's almost like it's looking at the data like they are absolute
