[postgis-users] Group intersecting lines

Dear all,

Can anyone offer some advice on how to group lines together that
intersect?  What I would like to achieve is a grouping where all
connected lines are added to the one group and a disconnected set of
connecting lines would be added to another group (and so on).  Can I
do this using a GROUP BY clause?
