#282: Change ~= Operator to be a BBOX Only Test
---------------------+------------------------------------------------------
Reporter: pramsey | Owner: pramsey
Type: defect | Status: new
Priority: high | Milestone: postgis 2.0.0
Component: postgis | Version: trunk
Keywords: |
---------------------+------------------------------------------------------
Right now the assumed behavior of ~= is an index-assisted exact equality
check. As a result, unlike all the other GiST operators, it requires a re-
check, which means that all our operators end up stuck with a re-check.
Having no re-check can lead to odd behavior (#253) when combining the
indexed operator call with an un-indexed operator call (#253). It would be
better to have all our GiST operators consistently work on bounding boxes
only. This will be a slight breaking behavior change.
