Comment(by strk):

 So one idea is for functions like ST_AddEdgeNewFaces, ST_AddEdgeModFaces,
 ST_AddEdge and the like to all use a common "edge adder" function which
 would keep track of how many primitives are added and run ANALYZE <table>
 after every <X> additions in <table>. Since every primitive table has an
 id, driven by a sequence, it could be relatively inexpensive to do, using
 a modulo operation.
