#4684: concurrent topology construction routine may result in invalid topology
-----------------------+---------------------------
Reporter: laopsahl | Owner: strk
Type: defect | Status: new
Priority: medium | Milestone: PostGIS 3.0.4
Component: topology | Version: 3.0.x
Resolution: | Keywords:
-----------------------+---------------------------
Comment (by strk):
It looks like another effective approach to prevent invalidities would be
to ensure every transaction possibly modifying a topology runs with
SERIALIZABLE TRANSACTION ISOLATION LEVEL. In that case it looks like all
possible invalidities will be prevented by a serialization_failure
exception.
