Error in ST_Intersects: lwgeom_covers_lwgeom_sphere: only POLYGON and POINT types are currently supported

[realityexists]

When I run the attached query I get

ERROR:  lwgeom_covers_lwgeom_sphere: only POLYGON and POINT types are currently supported

The interesting thing is that running it on either one of the polygons works (ST_Intersects returns false). It's only when running on both in the same query that the error occurs.

This is just a poor error message. What it should perhaps say is "only POINT-IN-POLYGON tests area supported". Basically one argument has to be a point, the other argument a polygon. Or, wait a sec, this isn't on ST_Covers, but on ST_Intersects? I'll look closer.

Should be happy at r10190
