ST_AddIsoNode — Adds an isolated node to a face in a topology and returns the nodeid of the new node. If face is null, the node is still created.
Adds an isolated node with point location
to an existing face with faceid
to a topology
and returns the nodeid of the new node.
If the spatial reference system (srid) of the point geometry is not the same as the topology, the
is not a point geometry, the point is null, or the point intersects an existing edge (even at the boundaries) then an exception is thrown. If the point already
exists as a node, an exception is thrown.
is not null and the
is not within the face, then an exception is thrown.
