Comment:

 gabrimonfa,

 I don't think this is a bug.  First of all you are using = instead the hex
 compare or ST_Equals.  The = operator just compares float4 bounding boxes
 in prior versions.

 In 2.0 this is a double precision box so its not a surprise 2.0 gives a
 more correct answer.

 If you get true with ST_Equals, then there is an issue, otherwise I'll
 just dismiss this as a limitation for float4 boxes.  Paul can confirm.
