| hi, thanks for writing
I'm doing research about spatial access methods( reading a lot of papers and
programming a lot too ) but also I want to know how can I add my new data
structure( if someday i get it, of course =) ) in the postgresql;in order to
do so, first I have to know how the R-tree works with the postgreql, I mean,
I already know the R-tree algorithms but I don't know how does the R-tree
interfaces with postgresql.
I hope you can help me
regards Jorge
