<!-- Converted from text/plain format -->
<P><FONT SIZE=2>I tried your test on my all_counties table and it worked fine. But I was doing it from pgadmin III. and I have left out that clusture thing you were doing. What does that do? :)<BR>
<BR>
create table ttt as select * from all_counties;<BR>
create index ttt_gix on ttt using gist(the_geom);<BR>
cluster ttt using ttt_gix;<BR>
select count(*) from all_counties;<BR>
<BR>
-- gives me 3141 records --<BR>
<BR>
I guess we must have similar county tables since we have the same record count.<BR>
<BR>
My projection is in 3395.<BR>
