[postgis-users] query gist bbox

[Till Kirchner]

  Hello together,

I would like to visualize and query the bboxes used by a gist (rtree) index.

I thought there should be an easy and fast way to get the maximum extend 
of geometries stored in a column by simply
querying the corners of the bbox which covers all data used by the index.

Is there a function which allows to get information about bboxes used by 
a gist index?

Thanks in advance

Till
