Hello all, I've been tring to speed up the restore operation of my database without success. I have a 200MB dump file obtained with 'pg_dumpall --clean --oids'. After restore is produces a database with one single table (1.000.000) rows. I have also some indexes on that table. that's it. It always takes me about 20 minutes to reload the data, whatever settings I change. I have so far touched these settings: - fsync = off - shared_buffers = 24MB - temp_buffers = 24Mb - maintenance_work_mem = 128MB - full_page_writes = off - wal_writer_delay = 10000 - checkpoint_segments = 200 - checkpoint_timeout = 1800 - autovacuum = off I started with a default instalation. first I changed fsync to off, then I started touching other cfg params. but I always get around 20 minutes (21, 19, 18).... Can I expect these 20 minutes to be significantly reduced ? What other cfg paramenters shoud I touch ? Can anyone shed some light on this ? any faster approach to upgrade from 8.1 to 8.3 ? thank you Joao -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
