We are in the process of upgrading our 7.3.4 servers to 8.1, and I wanted to have a sanity check ran against my config file. Do you see any issues with these configs? Our servers are Dell 2650/2850's with dual processors and 8-12 GB memory. postgresql.conf listen_addresses = '*' # what IP address(es) to listen on; max_connections = 256 shared_buffers = 32768 # min 16 or max_connections*2, 8KB each max_prepared_transactions = 256 # can be 0 or more work_mem = 4096 # min 64, size in KB maintenance_work_mem = 1048576 # min 1024, size in KB max_fsm_pages = 8000000 # min max_fsm_relations*16, 6 bytes each max_fsm_relations = 5000 # min 100, ~70 bytes each vacuum_cost_delay = 10 # 0-1000 milliseconds vacuum_cost_limit = 1000 # 0-10000 credits wal_buffers = 64 # min 4, 8KB each checkpoint_segments = 256 # in logfile segments, min 1, 16MB each checkpoint_timeout = 1800 # range 30-3600, in seconds effective_cache_size = 766980 # typically 8KB each random_page_cost = 2 # units are one sequential page fetch constraint_exclusion = on redirect_stderr = on # Enable capturing of stderr into log log_directory = 'pg_log' # Directory where log files are written log_truncate_on_rotation = on # If on, any existing log file of the same log_rotation_age = 1440 # Automatic rotation of logfiles will log_rotation_size = 0 # Automatic rotation of logfiles will log_min_duration_statement = 0 # -1 is disabled, 0 logs all statements log_connections = on log_disconnections = on log_duration = on log_line_prefix = '%d,%u,%p,%m,%c,%l,%s,%x,%i,' # Special values: log_statement = 'all' # none, mod, ddl, all stats_start_collector = on stats_command_string = on stats_block_level = on stats_row_level = on stats_reset_on_server_start = on autovacuum = off # enable autovacuum subprocess? lc_messages = 'C' # locale for system error message lc_monetary = 'C' # locale for monetary formatting lc_numeric = 'C' # locale for number formatting lc_time = 'C' # locale for time formatting add_missing_from = on I have upped the following parameters to help speed up our conversions, is there any issues leaving them set to these values after our conversion to 8.1? maintenance_work_mem to 1GB (1048576) checkpoint_segements to 256 checkpoint_timeout to 1800 seconds (30 minutes) Thanks, Chris
