Oh right, there is a lock on reads to the index with REINDEX, so the index is useless. I missed that detail. A table without a readable index is probably no good for your situation. Here is another helpful doc page to explain locks: http://www.postgresql.org/docs/8.4/static/explicit-locking.html Also, to change the doc version, just edit the URL to your version (e.g., replace 8.4 with 8.2 or whatever). -Mike _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
