Subject: R-tree and start/end queries

Message-ID: <BF571628.EF19%sdavis2@mail.nih.gov> (raw)

I have a table like:

Create table gf (
    pk    serial,
    start int,
    end   int,
    gf    varchar
);

I want to do queries along the lines of:

"find all gf that overlap with (10000,20000)" or
"find all gf that overlap with each other"

And others.  I have read over the documentation, but I still remain unclear
about how to implement R-tree indexing in this situation.  Any suggestions?

Thanks,
Sean
