GHA latest run failing on GDAL

[robe]

I'm assuming something changed in GDAL (or PG18), most likely GDAL because PG17 geos-main/gdal 3.9 run is fine, but latest which tests against PG18 and GDAL head is erroring with:

 raster/test/regress/loader/Projected .... failed ( test: running raster2pgsql output: /tmp/pgis_reg/loader.err)
-----------------------------------------------------------------------------

Debbie looks to be fine and she tests against PG18 too so this must be a GDAL issue.
