[postgis-users] PostgreSQL 8.3 GiST Bug

[Paul Ramsey]

Important information for PostGIS users! If you are on the PostgreSQL
8.3 series, upgrade to 8.3.5 as soon as possible, as earlier releases
contain a GiST index bug which may cause data to occasionally not show
up in spatially indexed searches.

This bug will only affect tables that have had records deleted and
updated and new data inserted, so people using PostGIS in a primarily
read-only manner won't see it, but folks with changeable data may run
into it.
