Have you tried using convexhull(geometry)? Given a collection of points,
it'll return a polygon where every point is guaranteed to be inside the
polygon.
ie.
SELECT convexhull(collect(makepoint(x,y))) FROM mytable;
That's the point, I don't have them on a table. I mean, (x,y) pairs
will came on plain text. Must I insert them on a temp table? There's
no chance to make a polygon from (x,y) pairs "on the fly"?
Sorry if my question is too dumb, I don't have experience with all this stuff.

Thanx a lot in advance.
