PGAGROAL.CONF(5) File Formats Manual PGAGROAL.CONF(5) NAME pgagroal.conf - Main configuration file for pgagroal DESCRIPTION pgagroal.conf is the main configuration file for pgagroal. The file is split into different sections specified by the [ and ] characters. The main section is called [pgagroal]. Other sections specifies the PostgreSQL server configuration. All properties are in the format key = value. The characters # and ; can be used for comments; must be the first character on the line. The Bool data type supports the following val- ues: on, 1, true, off, 0 and false. OPTIONS The options for the main section are host The bind address for pgagroal. Mandatory port The bind port for pgagroal. Mandatory unix_socket_dir The Unix Domain Socket location. Mandatory metrics The metrics port. Default is 0 (disabled) metrics_cache_max_age The number of seconds to keep in cache a Prometheus (metrics) response. If set to zero, the caching will be disabled. Can be a string with a suffix, like 2m to indicate 2 minutes. Default is 0 (disabled) metrics_cache_max_size The maximum amount of data to keep in cache when serving Prometheus responses. Changes require restart. This parameter determines the size of memory allocated for the cache even if metrics_cache_max_age or metrics are disabled. Its value, how- ever, is taken into account only if metrics_cache_max_age is set to a non-zero value. Supports suffixes: B (bytes), the default if omitted, K or KB (kilobytes), M or MB (megabytes), G or GB (gigabytes). Default is 256k management The remote management port. Default is 0 (disabled) log_type The logging type (console, file, syslog). Default is console log_level The logging level, any of the (case insensitive) strings FATAL, ERROR, WARN, INFO and DEBUG (that can be more specific as DEBUG1 thru DEBUG5). Debug level greater than 5 will be set to DEBUG5. Not recognized values will make the log_level be INFO. Default is info log_path The log file location. Default is pgagroal.log. Can be a strf- time(3) compatible string log_rotation_age The age that will trigger a log file rotation. If expressed as a positive number, is managed as seconds. Supports suffixes: S (seconds, the default), M (minutes), H (hours), D (days), W (weeks). A value of 0 disables. Default is 0 (disabled) log_rotation_size The size of the log file that will trigger a log rotation. Sup- ports suffixes: B (bytes), the default if omitted, K or KB (kilobytes), M or MB (megabytes), G or GB (gigabytes). A value of 0 (with or without suffix) disables. Default is 0 log_line_prefix A strftime(3) compatible string to use as prefix for every log line. Must be quoted if contains spaces. Default is %Y-%m-%d %H:%M:%S log_mode Append to or create the log file (append, create). Default is append log_connections Log connects. Default is off log_disconnections Log disconnects. Default is off blocking_timeout The number of seconds the process will be blocking for a connec- tion (disable = 0). Default is 30 idle_timeout The number of seconds a connection is been kept alive (disable = 0). Default is 0 max_connection_age The maximum number of seconds that a connection will live (dis- able = 0). Default is 0 validation Should connection validation be performed. Valid options: off, foreground and background. Default is off background_interval The interval between background validation scans in seconds. De- fault is 300 max_retries The maximum number of iterations to obtain a connection. Default is 5 max_connections The maximum number of connections (max 1000). Default is 1000 allow_unknown_users Allow unknown users to connect. Default is true authentication_timeout The number of seconds the process will wait for valid creden- tials. Default is 5 pipeline The pipeline type. Valid options are auto, performance, session and transaction. Default is auto auth_query Enable authentication query. Default is false failover Enable failover support. Default is false failover_script The failover script tls Enable Transport Layer Security (TLS). Default is false tls_cert_file Certificate file for TLS tls_key_file Private key file for TLS tls_ca_file Certificate Authority (CA) file for TLS libev The libev backend to use. Valid options: auto, select, poll, epoll, iouring, devpoll and port. Default is auto buffer_size The network buffer size (SO_RCVBUF and SO_SNDBUF). Default is 65535 keep_alive Have SO_KEEPALIVE on sockets. Default is on nodelay Have TCP_NODELAY on sockets. Default is on non_blocking Have O_NONBLOCK on sockets. Default is off backlog The backlog for listen(). Minimum 16. Default is max_connections / 4 hugepage Huge page support. Default is try tracker Track connection lifecycle. Default is off track_prepared_statements Track prepared statements (transaction pooling). Default is off pidfile Path to the PID file. If omitted, automatically set to unix_socket_dir/pgagroal.port.pid update_process_title The behavior for updating the operating system process title, mainly related to connection processes. Allowed settings are: never (or off), does not update the process title; strict to set the process title without overriding the existing initial process title length; minimal to set the process title to user- name/database; verbose (or full) to set the process title to user@host:port/database. Please note that strict and minimal are honored only on those systems that do not provide a native way to set the process title (e.g., Linux). On other systems, there is no difference between strict and minimal and the as- sumed behaviour is minimal even if strict is used. never and verbose are always honored, on every system. On Linux systems the process title is always trimmed to 255 characters, while on system that provide a natve way to set the process title it can be longer Danger zone disconnect_client Disconnect clients that have been idle for more than the speci- fied seconds. This setting DOES NOT take long running transac- tions into account. Default is 0 disconnect_client_force Disconnect clients that have been active for more than the spec- ified seconds. This setting DOES NOT take long running transac- tions into account. Default is off The options for the PostgreSQL section are host The address of the PostgreSQL instance. Mandatory port The port of the PostgreSQL instance. Mandatory primary Identify the instance as the primary instance (hint) tls Enable Transport Layer Security (TLS) support (Experimental - no pooling).
