Commit c4c340088 changed geometric operators to use float4 and float8
functions, and handle NaN's in a better way. The circle sameness test
had a typo in the code which resulted in all comparisons with the left
circle having a NaN radius considered same.
postgres=# select '<(0,0),NaN>'::circle ~= '<(0,0),1>'::circle;
?column?
----------
t
(1 row)
This fixes the sameness test to consider the radius of both the left
and right circle.
Backpatch to v12 where this was introduced.
