Just replace the version numbers with whatever you have. In my defence I've used msql but have no idea about postgresql and thinking there's probably a few things use it I asked. Looked later but didn't know about "zless" and as it was working didn't bother to extract it. I did now so next time I'll be less nervous. mick -- Key ID4BFEBB31

Re: buster upgraded postgresql
but how to find out what is this "cluster-name" for pg_ctlcluster, pg_dropcluster and pg_upgradecluster ? "pg_dropcluster [--stop] cluster-version cluster-name" "pg_upgradecluster oldversion name [newdatadir]" ? OK from the conf files assume cluster-name is '10/main' and '11/main' respectively ? -- Key ID4BFEBB31
