SQLedge: Replicate Postgres to SQLite on the Edge
#. SQLite WAL mode
From https://www.sqlite.org/isolation.html https://news.ycombinator.com/item?id=32247085 :
> [sqlite] WAL mode permits simultaneous readers and writers. It can do this because changes do not overwrite the original database file, but rather go into the separate write-ahead log file. That means that readers can continue to read the old, original, unaltered content from the original database file at the same time that the writer is appending to the write-ahead log

#. dolthub/dolt: https://github.com/dolthub/dolt
> Dolt can be set up as a replica of your existing MySQL or MariaDB database using standard MySQL binlog replication. Every write becomes a Dolt commit. This is a great way to get the version control benefits of Dolt and keep an existing MySQL or MariaDB database.
#. pganalyze/libpg_query: https://github.com/pganalyze/libpg_query :
> C library for accessing the PostgreSQL parser outside of the server environment
#. Ibis + Substrait [ + DuckDB ]
> ibis strives to provide a consistent interface for interacting with a multitude of different analytical execution engines, most of which (but not all) speak some dialect of SQL.
> Today, Ibis accomplishes this with a lot of help from `sqlalchemy` and `sqlglot` to handle differences in dialect, or we interact directly with available Python bindings (for instance with the pandas, datafusion, and polars backends).
> [...] `Substrait` is a new cross-language serialization format for communicating (among other things) query plans. It's still in its early days, but there is already nascent support for Substrait in Apache Arrow, DuckDB, and Velox.
#. benbjohnson/postlite: https://github.com/benbjohnson/postlite
> postlite is a network proxy to allow access to remote SQLite databases over the Postgres wire protocol. This allows GUI tools to be used on remote SQLite databases which can make administration easier.
> The proxy works by translating Postgres frontend wire messages into SQLite transactions and converting results back into Postgres response wire messages. Many Postgres clients also inspect the pg_catalog to determine system information so Postlite mirrors this catalog by using an attached in-memory database with virtual tables. The proxy also performs minor rewriting on these system queries to convert them to usable SQLite syntax.
> Note: This software is in alpha. Please report bugs. Postlite doesn't alter your database unless you issue INSERT, UPDATE, DELETE commands so it's probably safe. If anything, the Postlite process may die but it shouldn't affect your database.

Looking For Personal Database
Check IDE and GUI sections of https://github.com/mgramin/awesome-db-tools, some of them should be able to work with SQLite. My use case is different from yours (I'm developer and have no need for manual data entry) so I'm not sure what's best for you, try them yourself.

Lazy beginner MySQL dev wants opinions
I think sharing database access across Internet is quite dangerous decision because of security. Instead of LAMP (or something like that) you might to use special tools or platforms for building/generating API or even a whole application over your DB https://github.com/mgramin/awesome-db-tools (API and "Application platforms" sections)

Pgroll: zero-downtime, undoable, schema migrations for Postgres
Forr postgres, how does the schema diffing aspect compare to migra?
https://github.com/djrobstep/migra
I'm asking because, although migra is excellent and there are multiple migrations tools based on it (at least https://github.com/bikeshedder/tusker and https://github.com/blainehansen/postgres_migrator), issues are piling up but development seem to be slowing down

Supabase Local Dev: migrations, branching, and observability
Weโve extended the CLI migration feature and added Dashboard support. Database migrations give you a way to update your database using version-controlled SQL files. Weโve built a lot of tooling around our migrations, including reparation, migration cleanup using the squash command, and diffing (using migra) to generate a new migration or to detect schema drift.
- How do you handle schema migrations?

Tool for generating automatic migrations/schema diff

Diesel 2.1
Is this similar to migra? There's a tool written in Rust that calls it, postgres_migrator (there's also tusker)

Prisma laying off 28% staff
If you wish to auto-generate migrations, there are declarative schema change tools available for most relational databases. I'm the creator of Skeema [1] which provides them for MySQL, but there are options for other DBs too [2][3][4].
Prisma's migration system actually partially copied Skeema's design, while giving credit in a rather odd fashion which really rubbed me the wrong way: "The workflow of working with temporary databases and introspecting it to determine differences between schemas seems to be pretty common, this is for example what skeema does." [5]
While I doubt I was the first person to ever use that technique, I absolutely didn't copy it from anywhere, and it was never "pretty common". I'm not aware of any other older schema change systems that work this way.

Ask HN: ORM or Native SQL?
The best solution I've ever seen is this Rust library https://github.com/cornucopia-rs/cornucopia
You write plain SQL for you schema (just a schema.sql is enough) and plain SQL functions for your queries. Then it generates Rust types and Rust functions from from that. If you don't use Rust, maybe there's a library like that for your favorite language.
Optionally, pair it with https://github.com/bikeshedder/tusker or https://github.com/blainehansen/postgres_migrator (both are based off https://github.com/djrobstep/migra) to generate migrations by diffing your schema.sql files, and https://github.com/rust-db/refinery to perform those migrations.
Now, if you have simple crud needs, you should probably use https://postgrest.org/en/stable/ and not an ORM. There are packages like https://www.npmjs.com/package/@supabase/postgrest-js (for JS / typescript) and probably for other languages too.
If you insist on an ORM, the best of the bunch is prisma https://www.prisma.io/ - outside of the typescript/javascript ecosystem it has ports for some other languages (with varying degrees of completion), the one I know about is the Rust one https://prisma.brendonovich.dev/introduction

I greatly dislike ORMs, but I find myself wanting ORM agnostic SQL migration tools. What do you use to perform RDBMS table migrations outside of an ORM?
I really liked the idea proposed in https://github.com/djrobstep/migra but havenโt used it yet.

How to sustainably developer SQL database code (schemas, functions, ...)?
I'd love to be able to be able to declaratively make changes directly in the table create commands instead of manually creating new migration scripts every time. I've found migra (we use PostgreSQL) and it seems to be exactly what I'm looking for. I'm curious about other people's experience and why things like Migra are the norm.
