Memory leak fixes for db_postgres.nim

I've fixed some memory leaks in db_postgres.nim. I had a long running service that kept running out of memory, and I noticed several Postgres processes were at their maintenance_work_mem at the same time (I think this is because of single-row mode). The pull request has just been merged:

How to create a mutable object prefrably without ref

Thanks @amadan and @Stefan_Salewski! Interesting! In the Nim community what is more commonly used when you want to create a class-like "thing", i.e. a data structure with a fix number of fields and a couple of methods operating on this structure? Objects handed into the methods as `var`s or `re

Plans for improving tagged enum (ADT) syntax?

My view is that in general people shouldn't use "raw" object variants in important code. They should either stick to some guidelines for using them (this is not a rare thing in code) or wrap around those guidelines with macros. As an example of a guideline: each branch must have a single field,

Choosing Nim out of a crowded market for systems programming languages

Exceptional engineering does not imply or require novelty. Taking existing ideas and applying them effectively within real-world constraints is what separates an exceptional _engineer_ from a theoretician. How is longevity "always proven false" when neither of us even specified the length of tim

Choosing Nim out of a crowded market for systems programming languages

ok, trying again. is this simple enough? 1. JVM is not exceptional engineering, it is an ordinary derivative work based on work from the 1960's. 2. Some developer after you will reinvent the JVM and declare it exceptional engineering. 3. Pronouncements of longevity are always proven false.

Electron in nim like Tarui and Wails v2

Update to my previous message, I was wrong. I misunderstood the goal of libraries like tauri, wails, nimview, webgui. I though those framework would allow you to develop UI in Rust/Go/Nim with HTML/CSS. But as it turned out, it's not the case. The UI had to be in JS or compile-to-JS. You can't

nimble master

It seems that `nimble` assumes the default branch of a new repo of `git` is `master` but I set it to `main`. So I wasn't able to use `nimble publish` until I changed it back to `master`. Is there a way to tell `nimble` to change the name?

Data is always a way to improve an argument, but you probably want some in there. :-) Nim needs some kind of AST grep..Maybe someone is working on one already?

I personally don't like using the word `enum` for variants, since they're in general not “enumerated”. Nim uses terminology more correctly than most programming languages, no need to ruin it.

It's not that I avoid case object declarations, it's just that type sections and object declarations are rare in general. Probably you're onto something though, maybe it's as simple as: type Either[E, T] = enum None(E) Some(T) Tree = ref enum
