# # PostgreSQL configuration file # ----------------------------- # # This file consists of lines of the form # # name = value # # (The `=' is optional.) White space is collapsed, comments are # introduced by `#' anywhere on a line. The complete list of option # names and allowed values can be found in the PostgreSQL # documentation. The commented-out settings shown in this file # represent the default values. # Any option can also be given as a command line switch to the # postmaster, e.g., 'postmaster -c log_connections=on'. Some options # can be changed at run-time with the 'SET' SQL command. #======================================================================== # # Connection Parameters # tcpip_socket = true #ssl = false max_connections = 32 port = 5432 hostname_lookup = true show_source_port = true #unix_socket_directory = '' #unix_socket_group = '' #unix_socket_permissions = 0777 virtual_host = '127.0.0.1' #krb_server_keyfile = '' # # Shared Memory Size # shared_buffers = 64 # 2*max_connections, min 16 max_fsm_relations = 100 # min 10, fsm is free space map max_fsm_pages = 10000 # min 1000, fsm is free space map max_locks_per_transaction = 64 # min 10 wal_buffers = 8 # min 4 # # Non-shared Memory Sizes # sort_mem = 512 # min 32 vacuum_mem = 8192 # min 1024 # # Write-ahead log (WAL) # #wal_files = 0 # range 0-64 #wal_sync_method = fsync # the default varies across platforms: # # fsync, fdatasync, open_sync, or open_datasync #wal_debug = 0 # range 0-16 #commit_delay = 0 # range 0-100000 #commit_siblings = 5 # range 1-1000 #checkpoint_segments = 3 # in logfile segments (16MB each), min 1 #checkpoint_timeout = 300 # in seconds, range 30-3600 #fsync = true # # Optimizer Parameters # #enable_seqscan = true #enable_indexscan = true #enable_tidscan = true #enable_sort = true #enable_nestloop = true #enable_mergejoin = true enable_hashjoin = true #ksqo = false #effective_cache_size = 1000 # default in 8k pages #random_page_cost = 4 #cpu_tuple_cost = 0.01 #cpu_index_tuple_cost = 0.001 #cpu_operator_cost = 0.0025 # # GEQO Optimizer Parameters # #geqo = true #geqo_selection_bias = 2.0 # range 1.5-2.0 #geqo_threshold = 11 #geqo_pool_size = 0 # default based on #tables in query, range 128-1024 #geqo_effort = 1 #geqo_generations = 0 #geqo_random_seed = -1 # auto-compute seed # # Debug display # #silent_mode = false log_connections = true log_timestamp = true #log_pid = false debug_level = 0 # range 0-16 debug_print_query = true #debug_print_parse = false #debug_print_rewritten = false #debug_print_plan = false #debug_pretty_print = false # requires USE_ASSERT_CHECKING # debug_assertions = false # # Syslog # # requires ENABLE_SYSLOG #syslog = 0 # range 0-2 #syslog_facility = 'LOCAL0' #syslog_ident = 'postgres' # # Statistics # #show_parser_stats = false #show_planner_stats = false #show_executor_stats = false #show_query_stats = false # requires BTREE_BUILD_STATS #show_btree_build_stats = false # # Access statistics collection # #stats_start_collector = true #stats_reset_on_server_start = true #stats_command_string = false #stats_row_level = false #stats_block_level = false # # Lock Tracing # #trace_notify = false # requires LOCK_DEBUG #trace_locks = false #trace_userlocks = false #trace_lwlocks = false #debug_deadlocks = false #trace_lock_oidmin = 16384 #trace_lock_table = 0 # # Misc # #dynamic_library_path = '$libdir' #australian_timezones = false #authentication_timeout = 60 # min 1, max 600 #deadlock_timeout = 1000 #default_transaction_isolation = 'read committed' #max_expr_depth = 10000 # min 10 #max_files_per_process = 1000 # min 25 #password_encryption = false #sql_inheritance = true #transform_null_equals = false
