System behind a database address (TCP, DNS, or host list), then it isīetter if PgBouncer also uses connections in that manner, thusīy default, PgBouncer tracks client_encoding, datestyle, timezone, standard_conforming_stringsĪnd application_name parameters per client. This gives best performance if you haveĪ single server serving a database. So that few connections get the most load.

Note: ulimit does not apply in a Windows environment. Search for ulimit in your favorite shell man page. Still, it means you should set the number ofįile descriptors to a safely high number. The theoretical maximum should never be reached, unless somebody deliberatelyĬrafts a special load for it. Max_client_conn + (max pool_size * total databases) The server, the theoretical maximum used is: If each user connects under its own user name to Number of file descriptors potentially used is more than Operating system might also have to be increased. When this setting is increased, then the file descriptor limits in the Maximum number of client connections allowed. Spanning multiple statements are disallowed in this mode. statement Server is released back to pool after query finishes. transaction Server is released back to pool after transaction finishes. session Server is released back to pool after client disconnects. Specifies when a server connection can be reused by other clients. PgBouncer is started as root or if it’s already running as the given user. If set, specifies the Unix user to change to after startup. Ignored for sockets in the abstract namespace.

Specifies a list (comma-separated) of addresses where to listen for TCP connections. Without pidfile set, daemonization ( -d) is not allowed. Use the command-line option -q or -d for that. Note that setting logfile does not by itself turn off logging to On Windows, the service must be stopped and started. The log file is kept open, so after rotation, kill -HUP The characters “ ”Īnd “#” are not recognized as special when they appear later in the line. Starting with “ ” or “#” are taken as comments and ignored. The configuration file is in “ini” format.
