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;
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,

Subject: [postgis-devel] CLUSTER in 8.3
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!
