pgbouncer | pgbouncer multhread version | SQL Database library

We have a setup where we are running 6 PgBouncer processes and our performance benchmarks degrade linearly with time. The longer PgBouncer has been running, the longer the connections to Postgres exist results in slower response times for the benchmark. We have a multi-tenant schema separated database with 2000+ relations. We are configured for Transaction Mode pooling right now. Over time, we see the memory footprint of each Postgres process climb and climb and climb, and again, this results in poorer performance.

We have tried to be more aggressive in cleaning up idle connections with the following settings:

I have a postgres database (version 9.2) running on Centos 6.9. I am running pgbouncer version 1.6.1

When I try connect to postgres using datagrip from my Mac, I get:

My pgbouncer.ini file:

TL;DR: update your bin/qgtunnel.

I've recently noticed an increase in my web dyno's memory usage. After digging a bit, I could see that the LD_PRELOAD variable that should be set with heroku-buildpack-jemalloc was not set correctly. I used a tiny script (bin/show_preload) that helped me debug that and trace which program was overriding LD_PRELOAD.

I am using this helm chart to deploy airflow https://github.com/apache/airflow/tree/master/chart

Apache Airflow version: 2.0.0

Kubernetes version: v1.19.4

What happened: I get this error when try to execute tasks using kubernetes

I want to run php-fpm in a docker container, but get an error message after starting the container:

Fatal error: Uncaught PDOException: could not find driver.

I use php7.4 with event engine and a postgres database in a separate container (I use docker-compose to start them all) and are working on ubuntu20.04.

The weird thing is: My collegues installed the same stuff without having this error, so the error cannot come from an incorrect docker file.

What I tried so far:

• I can connect to the database with psql from the shell.
• I printed out all modules that are loaded in the container, and they include pdo and pdo_pgsql.

The error refers to this method:

I currently have a problem with properly load balance open TCP sessions (created by the RoR application) to dynamically created Aurora Postgresql read-replicas.

The issue with this is when TCP connections are already established to one read-replica, another read-replica is created. After that traffic from the first replica will not be distributed evenly to second one, since TCP connections are already established with first replica.

Attached chart represents current infrastructure setup. Please note that between read-replicas (servers) and application (client) there is a load balancer, provided by the Aurora service, which is based on DNS round-robin.

I've tried pgbouncer, pgpool and multiple Ruby gems (makara, fresh_connection), but none of them were able to load balance nor eliminate long lived TCP connections..

I went through many articles and they helped investigate and confirm the issue; however none of them present a solution.

So... as you can see I've tried obey this problem from application and network perspective, unfortunately without luck. Has anyone had the same problem?

EF registers as scoped service, which means it creates many short connections to database. One http request - one connection. PostgreSQL doesn't handle a lot of concurrent connections very well. Like a maximum of 100. Is PgBouncer needed for .NET Core applications with Entity Framework (Npgsql)? PgBouncer manages the connection pool. Or can Npgsql manage the connection pool correctly? Or is this only relevant for Python and PHP? Thanks!

i'm working on a chat application using django Channels and reconnecting-web-socket the app works fine locally but when deployed to heroku the site works fine but the web socket closes before connection is established and sometimes it works fine.

it tries to connect and says websocket open and established
