Hi, How can I have my table clustered as records are being insert/updated (per transaction). I tried doing so with creating an index using pgAdmin III, and it generated the following SQL: CREATE INDEX someindex ON mytable (m2); ALTER TABLE mytable CLUSTER ON someindex; Now, above DID NOT cluster my table and I had to run PostgreSQL's own cluster command to have it clustered. According to my db-savvy colleagues (who use SQL Server), a live cluster is a must have on a high traffic large db and they are questioning this feature of PostgreSQL. I'd appreciate comments here, Thanks, Mike
