Try using GiST rtree (examples in contrib), GiST supports multi-key indexes.

I'm using PostgreSQL 7.3.2 and I need to create a R-Tree index that uses more than one column in a table.
When I run the instruction it appears this message bellow:
DefineIndex: access method "rtree" does not support multi-column indexes
How can I solve this problem ? Is it a limitation of PostgreSQL or the R-Tree concept ?
Thank you in advance.
