Description ¶
It would be useful to have the ability to build an infinite line that passes through two points.
Some people need find point that would lie on a segment's continuation(for example if they need to extend that segment indefinitely and see if it would hit a different geometry along the way, maybe a polygon). And currently it seems that the way this is done is by computing the segment's bearing and new length, and are extending their lines that way.
Since PostgreSQL has +/- Infinity
described in the docs for floating point types, maybe those could be used to define such a line.
