This is 8.2.6 in Fedora 8 and the same database with which there were performance problems when migrating to 8.3. The migration was not done. The thread was this: http://archives.postgresql.org/pgsql-general/2008-01/msg00508.php The database performance slowly degrades and after two weeks i issue a reindex on the database and the performance gets back to normal. I have been doing this for ages and i don't remember in which version this degradation behavior appeared, perhaps 8.0 I'm not sure. Every two or three months the reindex gets slow even for small tables then i reboot the machine and it gets back to normal reindex performance. This happened in more than one version of Fedora and Postgresql and in two different production machines with very different configurations. Now what is happening is that reindex does not finish even with a small 6,500 rows table and after a reboot. In top there is no CPU or memory usage by postmaster and vmstat shows no disk activity. I recently had a crash during a bulk insert when i updated to the 2.6.24.3-12.fc8 kernel. I rebooted and Postgresql did its thing to recover and everything was working. I made the previous kernel, 2.6.23.15-137.fc8, the default in grub.conf and rebooted. How do I know if the database is corrupted? Since there is no explain for reindex or vacuum i don't know what is happening. How to debug?
