I have a very large table (~5GB, 100mm rows) on which I am creating an index on an int4 column: CREATE INDEX CONCURRENTLY rums_idx2 ON rums USING hash (user_id); The process has been running for about two days, and the index has been growing; when I run du i can see that it is ~2GB on the filesystem, though it is incrementing at a snail's pace; maybe 500kB per minute or so. From posts I've read it seems abnormal that it should be taking this long. My suspicion is that the hash function is what is slowing it down or maybe I should have fsync=off. I have shmmax at about 256MB and my conf is as follows: shared_buffers = 224MB # min 128kB or max_connections*16kB work_mem = 112MB # min 64kB maintenance_work_mem = 212MB # min 1MB Info: postgresql-8.2 Linux vostro200 2.6.20-15-server #2 SMP Sun Apr 15 07:41:34 UTC 2007 i686 GNU/Linux 1GB RAM Intel CoreDuo Any ideas? ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
