(Sorry if message threading is a bit off; I'm replying from a different mail account as the previous post, so the "ref" header won't match.) Well I tried /usr/bin/pg_ctl -D /var/lib/pgsql/data start -l /tmp/pglogfile and it just says server starting and then... nothing. It seems to quit immediately. The logfile, /tmp/logfile exists, but is empty. (I noticed the previous logfile, "pgstartup.log", was still the same and hadn't changed since a few hours earlier, so the "modified" timestamp confirmed, so it wasn't being updated any more.) As where I did get the installer of Postgres for CentOS: I don't quite remember the details, as it has been running well for several months. But I got the idea from one of the many blog posts about it, such as these: http://blog.lystor.org.ua/2010/05/upgrading-postgresql-81-to-84-centos-55.html http://www.if-not-true-then-false.com/2010/howto-install-postgresql-8-4-database-server-on-centos-fedora-red-hat/ I think it just comes from one of the unofficial CentOS repositories. Like I said, it has been running well for months and the latest upgrade was unrelated to PostGres. It may have been some manual tweak I did a few weeks ago... PostGres hadn't been restarted since then. If I knew what it was complaining about, I might be able to fix it. I have already made a backup of the /var/lib/pgsql/data subdirectory, I might just remove all of Postgres, and then reinstall. Luckily this is a development machine, but as we don't know what causes the problem we fear we might one day face the exact same problem where it does matter: on a production machine. So we'd like to know exactly what went wrong... -- Bart Lateur bart.lateur@xxxxxxxxxx -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
