I am having problems starting up Postgres and am getting the following error: 2010-12-01 08:36:42 EST LOG: database system was shut down at 2010-11-29 17:38:17 EST 2010-12-01 08:36:42 EST FATAL: invalid cache id: 19 2010-12-01 08:36:43 EST FATAL: the database system is starting up 2010-12-01 08:36:43 EST LOG: startup process (PID 640) exited with exit code 1 2010-12-01 08:36:43 EST LOG: aborting startup due to startup process failure Prior to shutting down the database, the log file reported the following message: 2010-11-29 12:39:17 EST ERROR: database is not accepting commands to avoid wraparound data loss in database "fps_data" 2010-11-29 12:39:17 EST HINT: Stop the postmaster and use a standalone backend to vacuum that database. I had multiple auto-vacuum instances running, but it looks like they were unable to keep up. I found some reference to bug # 5718 (http://archives.postgresql.org/pgsql-bugs/2010-10/msg00185.php) that lists a patch, but I am unfamiliar with how to apply the referenced patch, or if it will help. I am running Postgres 9.0.0-1 on Windows XP courtesy of Enterprise DB. Hardware is 64bit, but I am running the 32bit version. Is this patch likely to help with startup? How does one apply it via windows, or could I just install Version 9.0.1-1 and get the same result?
