 Postgis 2.x now assumes that 0 represents an "unknown" srid.  So in our db
 we have an enforce_srid constraint that says the srid should be 0 when
 storing indoor features.

 Problem is geos intentionally doesn't output a 0 srid, here is the code:

 void
 WKBWriter::writeSRID(int SRID)
 {
     if (includeSRID && SRID != 0)
         writeInt(SRID);
 }

 This breaks our app because when it inserts a record to postgis it sends
 the new geometry using the wkb format.  Since geos doesn't emit the 0
 srid, the enforce constraint fails because the srid isn't set at all (and
 we want it to be 0).

 Could this check be removed to bring geos in line with postgis?
