Thanks,
I have my geom in table named segments.
I added upgis_lineshift function to my database and after use
SELECT upgis_lineshift(the_geom,10) As right_line from segments;
I get message like this:
ERROR: column "st_startpoint" does not exist
LINE 1: SELECT ST_Azimuth(ST_StartPoint?( $1 ), ST_EndPoint?( $1 ))
so I checked:
select AsText(ST_StartPoint(the_geom)) from segments;
and I get
astext
---------------------------------
POINT(-8.593025208 41.180818082)
POINT(-8.594827652 41.187632944)
POINT(-8.591823578 41.193090782)
POINT(-8.611950874 41.190119708)
POINT(-8.613796234 41.179203081)
POINT(-8.602809906 41.180559684)
(6 rows)
so ST_StartPoint exists and works well.
I don't know what is goin on :P
