 the last run I did in May for 3.1.9 release passed and was also testing
 GEOS 3.9 (3.9.4dev).

 I'm assuming something in GEOS 3.9 branch changed since this test hasn't
 changed since the 3.1.9 release.

 Changes since PostGIS 3.1.9 release in geos 3.9 branch are:

 https://github.com/libgeos/geos/commit/8fd3b5f7127ab3e38fdc4621cf1aedcfbc165e57
 (GEOSClipByRect)

 and

 https://github.com/libgeos/geos/commit/d6f53e6c6b5da324aeb7d84a6044012710926a26
 (Do not hide illegal argument exception in HeuristicOverlay )


 The difference looks harmless, just a change in error messages to provide
 location of conflict
