Subject: PgBouncer-Postgres : un supported startup parameter statement_timeout
Date: Wed, 16 Jul 2025 12:52:54 +0530
Message-ID: <CAKgGyB8iYj_JavbDD13-4PknNJPji+=tbmSjk=80ZtcZmr-2nw@mail.gmail.com> (raw)
Hi,
I am facing an issue with PgBouncer-Postgres setup,
*PgBouncer (PgBouncer 1.23.1 running on VM instance FreeBSD 14.2) and
PostgreSQL DB cluster on a virtual machine (PG version 16.0, RHEL 9.4) *.
My application backend is nodeJS which throws the following Error in the
nodejs console log: when connecting through pgbouncer to the backend
database server...
ERROR thrown:
my-node>* Failed to connect to PostgreSQL database transaction_db :
unsupported startup parameter: statement_timeout *{"code":"08P01",
"length":69, "name": "error", xx xx
my-node> error:[object Object ] {"timestamp":"15-07-2025 10:14:26"} x x xx
Note: The nodejs apps earlier directly establishing connections to the
PostgreSQL DB ( no such errors) now redirected via Pgbouncer throws
this error.
*The config parameters for pgbouncer as follows(correct me if any mistakes
made)*
[root@pgbouncer ~]# grep ^[^';;;'] /usr/local/etc/pgbouncer.ini
[databases]
transaction_db = host=dbmain.mydomain.com port=5444 dbname=transaction_db
[users]
[pgbouncer]
Logfile = /var/log/pgbouncer/pgbouncer.log
pidfile = /var/run/pgbouncer/pgbouncer.pid
listen_addr = *
listen_port = 5444
auth_type = md5
auth_file = /usr/local/etc/pgbouncer.users
admin_users = adminuser
stats_users = adminuser,
pool_mode = transaction
server_reset_query = DISCARD ALL
server_reset_query_always = 1
ignore_startup_parameters = extra_float_digits // I have added this also
or can I add these options too in the following line ?
;; ignore_startup_parameters = extra_float_digits, options,
statement_timeout, idle_in_transaction_session_timeout // doubt options
supported in latest versions ?
max_client_conn = 5000 // can I give this much high value ?
default_pool_size = 20
min_pool_size = 10
reserve_pool_size = 10
reserve_pool_timeout = 5
max_db_connections = 100
max_user_connections = 30
server_lifetime = 3600
server_idle_timeout = 600 // is this a low value or need to be increased ?
[root@pgbouncer ~]#
The config params of N*odeJS application which uses nodejs connection
pooling in* code as follows
the Node JS application using the following nodejs pooling configurations
for the application level
*cat app_10072025/config/pg-pool-config.js*
.......
*const poolOptions = { max: 10, min: 2, idleTimeoutMillis: 600000,
//Idle for 5Min connectionTimeoutMillis: 10000, //Reconnect 10sec
statement_timeout: 60000, //Query executiion 1 min acquire: 20000,
maxUses: 1000 //reconnect after 1000 queries};*
const pools = {
transaction_db: new Pool({
connectionString: `postgresql://${DB_USER}:${DB_PASSWORD}@
${DB_HOST}:${DB_PORT}/${DB_NAME_TRANSACTION_DB}`,
...poolOptions,
}),
};
..................................
Any hints and suggestions in the config params are most welcome.
Thank you,
Krishane
