Comment (by strk):

 robe2 about regression on invalid geometries, what would you expect from
 ST_Equals in that case ? A false, a null or an exception ? None of the
 relate operations are _guaranteed_ to return a specific value on invalid
 input, as it would require checking for validity and it's expensive.
