[postgis-users] Need a "polygon box" of a table instead of the bounding box that returns extent function

[Oscar Zamudio]

ha, ha!!,
My knowledge come from Maths ,and certainly not from Postgis!. The concept
of Convex Hull (in algorithms and math fields) is always applied to set of
points and I remember there was a big challenge to find a good method for
lines (some years ago). But I don't mind Math anymore, if this function
works to solve my problem, it will be ok for me.
I will let you know later about my results.
