#5366: GHA last coverage is failing on raster GDAL polygonize cUnit test
--------------------+---------------------------
 Reporter:  robe    |      Owner:  robe
     Type:  defect  |     Status:  new
 Priority:  medium  |  Milestone:  PostGIS 3.4.0
Component:  raster  |    Version:  master
 Keywords:          |
--------------------+---------------------------
 Given this has been working and we haven't made any changes since this
 failure, I'm suspecting something upstream changed, perhaps GDAL
 polygonize again

 Given debbie is not failing, I don't think it's PG16 at fault
