pgbouncer VS postgres

Thanks to MongoDB drivers all consistently providing connection monitoring and pooling functionality, external connection pooling solutions aren't required (ex: Pgpool, PgBouncer). This allows applications built using MongoDB drivers to be resilient and scalable out of the box, but based on what we understand regarding the number of connections applications establish to MongoDB clusters it stands to reason that at a certain point as our application deployments increase, so will our connections.

Pgbouncer - resolvia o problema do limite de conexões no postgres. Mas a API “saudável” manteve o número de conexões baixo o suficiente.

Pgbouncer maintainer here. Overall I think this is a great description of the tradeoffs that PgBouncer brings and how to work around/manage them. I'm actively working on fixing quite a few of the issues in this blog though

1. Named protocol-level prepared statements in transaction mode has a PR that's pretty close to being merged: https://github.com/pgbouncer/pgbouncer/pull/845

A common solution is connection pooling. Supabase currently offers pgbouncer which is single-threaded, making it difficult to scale. We've seen some novel ways to scale pgbouncer, but we have a few other goals in mind for our platform.

Great observation! :)

We worked upstream to have `search_path` properly handled (tracked per client) by pgbouncer.

I want to use this as a chance to bring attention to a GitHub issue that I think would help reduce friction for Neon:

https://github.com/neondatabase/neon/issues/4989

If the Neon driver were to allow us to easily pass in a localhost connection, the development and test experience would be easier. Perhaps Neon could swap to something like this internally: https://github.com/porsager/postgres.

Having run a local dev environment connected to Neon and tests connected to Neon got in our way of adoption. We'd prefer to develop and run tests against a regular Postgres localhost database.

To the PMs of Neon, put yourself in the shoes of a new developer thinking of giving Neon a try. What changes will I have to make to my code and my development workflow?

I'd push you to consider using postgres, slonik or similar for database queries. With these libraries, you just write SQL, but they perform input sanitization for you. So you can safely write:

Thanks Pier! Your comment saved me some frustration here :-D

There's a core client interface here:

On what makes it postgres.js faster, from author himself:

> it seems Postgres.js is actually faster than, not only pg, but of any driver out-there

When viewed as a DSL for set theory, views, CTEs, set-returning functions, et al are indeed proper first-class query abstractions.

When viewed through the lens of general purpose imperative or functional programming languages, it's easy to see how it can be seen as falling short.

I'll admit much of the tooling and driver APIs leave a lot to be desired.

Some tools do make good efforts though such as nested fragments in this driver.

I don't think this should turn in to an ORM or not debate, but there are plenty of reasons, especially for the crowd that would do anything to avoid ORMs. Just try to take a peek into the multitude of "ORMs are bad" articles / discussions.

For instance - I would love to be able to use https://github.com/porsager/postgres with sqlite.

Demonstrate how easily and accidentally one can make an SQL injection with these:

They've looked at Postgres.js (https://github.com/porsager/postgres) before — wouldn't mind if they enabled those other cases in the same way.
