#1774 closed enhancement (fixed)
Confusing error message from ST_ChangeEdgeGeom (lwpoly_from_lwlines: shell must have at least 4 points)

Description
The error is confusing as I'm changing an edge geometry so don't expect LWPOLY to have anything to do with it.
I guess it's about the isomorphic movement detection.

Ok the error is raised when passing a single-point edge as a replacement for an existing edge. It's surely non-isomorphic (even if the edge was closed, a face would disappear), but could be reported in a nicer way
