Hello,
I think if you try what I suggested last time, the combined use of the functions should return st_multiline for the object you want to identify.
SELECT gid, ST_GEOMETRYTYPE(ST_UNION((ST_DUMP(geom)).geom))
FROM your_table
GROUP BY gid
Regards,
Hug

Hello guys, I need to check if two lines are spatially separated but in the same geometry, for example when I open qgis and select one line two lines are selected not one (this lines are separated and even not touch each other), I try using st_numgeometries(my_line_geometry) on the db manager but always return 1, any suggest? Thanks before hands my friends.
