[postgis-devel] ST_LineLocatePoint with empty geom raise error

[Rémi Cura]

Honestly I don't care that much
,already wrote protections aggainst it.

It's just that the answer to the question what is the curvabs of a point on
this non exisiting line should be it doesn't exist,
not error, I don't know how to compute this.

Anyway a good error message would help anyway ;-)
Cheers,
Rémi-C
