I completely agree ! actually i face the need to split my database in 2
database engines just because i need RTree indexes ...
PostgresSQL is probably right (i not try it yet), but it's a very heavy
system, it's hard like oracle without the power of oracle !

so this feature in Firebird could be defintivelly be a greatest features !

and also i thing we can easily found some users to sponsor such
developpement

to finish, when i see how sqlite3 implemente their rtree index (only
with additionnal table), and with few hundreds of lines of code it's not
look like a "titan" project ...
