No, as someone already noted the VACUUM FULL is blocking anyway (and does not use this value at all). > Uncommented relevant values in postgresql.conf file are: > > shared_buffers = 15000 > work_mem = 512 I'd consider increasing this value a little - 0.5 MB seems too low to me (but not necessarily). > maintenance_work_mem = 131072 > fsync = on > effective_cache_size= 70000 Well, your server has 2GB of RAM and usually it's recommended to set this value to about 60-70% of your RAM, so using 540MB (25%) seems quite low. Anyway this is just a hint to PostgreSQL, it does not increase memory consumption or so - it's just an estimate of how much data are cached by kernel. Anyway, I don't expect these values have significant effect in case of the issue solved in this thread. regards Tomas
