#4540: ST_AsMVT silently drops json columns
-------------------------+---------------------------
 Reporter:  nextstopsun  |      Owner:  pramsey
     Type:  defect       |     Status:  new
 Priority:  medium       |  Milestone:  PostGIS 2.5.4
Component:  postgis      |    Version:  2.5.x
 Keywords:               |
-------------------------+---------------------------
 ST_AsMVT doesn't encode columns of type JSON/JSONB.
 It's output doesn't contain properties from json and no message is raised
 while encoding.

 MVT spec currently doesn't have this data type, but these types could
 first be cast to TEXT type and then encoded (i.e. tippecanoe does internal
 conversion to text for nested json properties).
