#3181: Output POINT EMPTY in WKB using NaN as coordinate values
-------------------------+---------------------------
 Reporter:  pramsey      |      Owner:  pramsey
     Type:  enhancement  |     Status:  new
 Priority:  high         |  Milestone:  PostGIS 2.2.0
Component:  postgis      |    Version:  trunk
 Keywords:               |
-------------------------+---------------------------
 Our old handling of overloading POINT EMPTY to convert into MULTIPOINT
 EMPTY results in outputs that are not actually consistent in type (that's
 a problem). A better hack would be using POINT(NaN NaN) to proxy for POINT
 EMPTY, since there's not much practical use for a POINT(NaN NaN) anyways.
 This means that database with "legitimate" POINT(NaN NaN) values would get
 them converted into POINT EMPTY on dump/restore, but that seems a small
 price to pay for the greater good.

 This was discussed in #3031.
