Hello !

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.
