Subject: [PATCH] Refs #36009 -- Adjusted
 gis_tests.geoapp.tests.GeoLookupTest.test_relate_lookup for bug in PostGIS.

ST_Relate() with PostGIS 3.5 and GEOS 3.13 gives a different result when
a series of calls are made vs. single call of the same function.

The fix for this is expected to be released in PostGIS 3.5.4 and 3.6.0.
