you install the PostgreSQL packages, it runs pg_createcluster for you. If you don't like the locale or encoding you used, you run pg_dropcluster and pg_createcluster as you did. The reason why your database did not work after doing this is probably obvious from your log files.
Hi Stuart,
<SNIP>
But I still come back to the locale issue. I am glad I was on the right track in replacing the cluster. Still, how could I have made UTF-8 the default encoding at install time? Maybe the very first step on a Kubuntu system should be to replace the cluster before doing anything else. Or maybe there is a locale setting that can be changed to ensure the pgsql package gets the 'right' cues?
