#3861: ST_AsGeoBuf and EMPTY
---------------------+---------------------------
 Reporter:  pramsey  |      Owner:  bjornhartnell

 Priority:  medium   |  Milestone:  PostGIS 2.4.0
Component:  postgis  |    Version:  trunk

 Looking over the code, it's not clear that ST_AsGeoBuf is doing the right
 thing with empty (or what the right thing is). The mapbox encode .js
 doesn't seem to have any special thinking about encoding empty, which
 means that probably `POINT EMPTY` will encode to something that is not
 valid and readable. It's possible that all other empties will work, since
 they'll have an npoints/ngeoms/etc that is written down as 0.
