#5990: Adding 2 lines to Postgis topology takes 2 hours in a production line we

* type: enhancement => defect
* version: 3.6.x => 3.0.x
Comment:
At the moment if you run `TopoGeo_addLinestring('topology',geom,0)` you
get to use the precision in the topology.topology record where
name='topology', and if that is also 0 you get to use an automatically
computed snapping tolerance.
For the record, I've filed #5993 for the specific action of adding the
`max_edges` parameter, so the issue title is clear. I guess we can keep
this issue open to request an improvement of performances for when you DO
want all those new edges.
