Actually I think the root of the problem was precisely that Linux does not issue any sort of cache flush commands to drives on fsync. There was some talk on linux-kernel of what how they could take advantage of new ATA features planned on new SATA drives coming out now to solve this. But they didn't seem to think it was urgent or worth the performance hit of doing a complete cache flush. -- greg ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
