[postgis-devel] CLUSTER in 8.3

[Obe, Regina]

Paul,

I hope its just you.  I don't recall running into any problems using
clustered indexes in 8.3 but then all my databases were restored from an
8.2 install but all the clusters look fine as far as I can tell.

I use the below syntax which I thought is the new syntax

ALTER TABLE sometable CLUSTER ON idx_sometable_geom_gist;
CLUSTER sometable;

I just dropped one of my indexes on a table in 8.3 and readded using
above and seems fine as far as I can tell.

When you say all row count - you mean of the table?

Hope that helps,
Regina

Is it just me, or has clustering on spatial indexes stopped working in
8.3? First, the syntax of CLUSTER has been changed, from "CLUSTER
[index] ON [table]" to "CLUSTER [table] USING [index]". Second, when I
run the new syntax using a gist index as the target, the index
disappears and all row count drops to zero!
