Is there a better way to handle postgres database errors such as foreign_key_violation and unique_violation?
i read somewhere that it is a good thing that the db throws errors such as foreign key constraint etc, if you are doing an explicit check first to see if the nickname exists and then doing the update then you are essentially doing 2 queries, i am not sure if their approach is correct or mine, thing is it starts throwing a bunch of constraint errors,am following the structure in this example like 100%

Show HN: I open-sourced the in-memory PostgreSQL I built at work for E2E tests
I've used pgmem https://github.com/oguimbal/pg-mem for the last couple of years for the same thing.

Ask HN: How do you test SQL?
I was wondering the other day how to classify tests that use a test double like pg-mem, which isn't a mock but isn't the Dockerized test DB either :

How to test nestjs modules?
In my case, I use TypeORM with PostgreSQL, and there's pg-mem to run an instance in memory, it supports most of the common functionality of PostgreSQL but you will need to do some adjustment to your code to be within the limits.

Working with offline data
Postgres in the browser is possible through pg-mem: "pg-mem is an experimental in-memory emulation of a postgres database" but it also suffers from no persistence. If you can persist to a file somewhere then read it in on startup (and if your local data isn't huge) this might work.

Haskell as a first timer - Am I missing something ? Or is something broken ?
Dont get me wrong: I am trying to contribute to opensource as well, so I get that supporting small projects can be demanding. There's nothing wrong in not spending your weekends on OS. But not asking for help, nor specifying that a project is unmaintained, nor even answering issues & pull requests for years feels just wrong.

pg-mem, an in memory postgres DB instance for your unit tests, is now bound to multiple libraries (Knex, Typeorm, Slonik, pg, pg-promise) ... suggestions for the next one ?
Okay, I had a bit of spare time,I've implemented that, and it is now available with [email protected]

Zero delay development & unit testing iterations
To get a glimpse of what I'm talking about, you can clone this repo and follow "Development" instructions (by the way this is a small OS lib I maintain, I wrote about it here)
