Comment (by robe):

 Mark,

 I disagree with you on this.  It has always been that ~= is an exact
 geometry operator.  I have always used it as such.  the = operator is the
 equality operator.  Our documentation has always said that ~= is true
 geometry equality operator -- its the only one of the operators that does
 not work on just bounding box there it is probably the only one that
 requires a recheck.

 I refer you to the docs -- see how in the index -- the ~= explicitly says
 geometry while the others say bounding box.

 http://www.postgis.org/documentation/manual-svn/ch07.html#Operators
 http://www.postgis.org/documentation/manual-svn/ST_Geometry_Same.html

 It is the ONLY operator that works against the geometry -- which makes it
 a bit different from the others.
