[postgis-users] line direction

[franco base]

Hi.
I know tgis function but doesn't work.
Myabe my question isn't correct.
I'd have a binary value according to the arc direction.
For example, in qgis I can view this information:
I can see an arrow on my arc according to direction.
I'd have the same using postgis.

Thanks
