The following bug has been logged online: Bug reference: 4567 Logged by: Regina Obe Email address: [EMAIL PROTECTED] PostgreSQL version: 8.3.5 Operating system: Numerous Description: Clustering on GIST INDEX clobbers records in table intermittently Details:
This doesn't always happen to me but does intermittently, and for others it happens all the time. Several of us have tried to recreate the issue. For me it happens once in a while on EL 4, 8.3.5 install. We have confirmed it happens on all GIST type indexes. We have not noticed this problem prior to 8.3.5 -- checkout this thread for details. http://postgis.refractions.net/pipermail/postgis-devel/2008-December/004284. html http://postgis.refractions.net/pipermail/postgis-devel/2008-December/004275. html http://postgis.refractions.net/pipermail/postgis-devel/2008-December/004283. html To recreate: 1) restart your postgresql service 2) run below test=# create temp table tmp as select st_makepoint(random(), random()) as the_geom from generate_series(1, 10000); SELECT test=# create index tmp_geom_idx on tmp using gist (the_geom); CREATE INDEX test=# analyze tmp; ANALYZE test=# select count(*) from tmp; count ------- 10000 (1 row) test=# cluster tmp using tmp_geom_idx; CLUSTER test=# analyze tmp; ANALYZE test=# select count(*) from tmp; count ------- 0 (1 row) Running the same exercise for me on 8.3.1 always seems to work correctly as far as I can tell. -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
