PostGIS WKB XYZM data works with WMS, breaks WFS output formats

Issue Type:	Bug
Affects Versions:	2.13.2
Assignee:	Jody Garnett
Components:	was

Reporter:	Jody Garnett

This is an interesting one, data was loaded into PostGIS via FME or similar workflow, it is perfectly valid WKB. WMS works fine as it makes use of ST_Force2D when accessing. WFS does not work out quite so well, data of the form: LINESTRING( X1 Y1 Z1 M1, X2 Y2 Z2 M2, X3, Y3 Z3 M3) Comes out in GeoJSON, GML2, GML3 as: LINESTRING( X1 Y1 Z1, M1 X2 Y2, Z2 M2 X3, Y3 Z3 M3) The fix should be to pay attention to the geometry dimension and compare / contrast with srs dimension to detect if measures are used.
