I see that PG has a one-shot CLUSTER command, but doesn't support continuously-updated clustered indexes. What I infer from newsgroup browsing is, such an index is impossible, given the MVCC versioning of records (happy to learn I'm wrong). I'd be curious to know what other people, who've crossed this same bridge from MSSQL or Oracle or Sybase to PG, have devised, faced with the same kind of desired performance gain for retrieving blocks of rows with the same partial key.
I just run clusterdb each weekend in a cron job... Chris
