[postgis-users] Lines spatially separated on the same geometry

[Luis Fernando Duque Quintero]

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.
