#3317: ST_LineMerge documentation should mention no support for M values
---------------------------+---------------------------
 Reporter:  pauldzy        |      Owner:  robe
     Type:  enhancement    |     Status:  new
 Priority:  low            |  Milestone:  PostGIS 2.1.9
Component:  documentation  |    Version:  2.1.x
 Keywords:  ST_LineMerge   |
---------------------------+---------------------------
 ST_LineMerge strips off M values from input geometries.  It would be nice
 if the documentation mentioned this.


 SELECT ST_AsEWKT(
    ST_LineMerge(
       ST_GeomFromEWKT('SRID=0;MULTILINESTRINGM((-29 -27 10,-30 -29.7
 20,-36 -31 30,-45 -33 40),(-45 -33 40,-46 -32 50))')
    )
 );
