What's New in SQLite 3.35
Hah, yeah PST v.s. PDT does make this harder.
At that point I'd switch to using additional custom SQL functions. I wrote a plugin called datasette-dateutil https://datasette.io/plugins/datasette-dateutil that exposes some extra functions, but it doesn't have anything useful for timezone calculations yet.
I've opened an issue: https://github.com/simonw/datasette-dateutil/issues/4

Choose Postgres Queue Technology
To make sure you that the message you are trying to retrieve hasn't been locked already by another worker.

SQL Maxis: Why We Ditched RabbitMQ and Replaced It with a Postgres Queue
SQLite is missing some features like `SELECT FOR UPDATE`, but you can work around some issues with a few extra queries. I wrote litequeue[0] with this specific purpose. I haven't been able to use it a lot, so I don't have real-world numbers of how it scales, but the scaling limits depend on how fast you can insert into the database.

What's New in SQLite 3.35
The `RETURNING` is so awesome! I'm implementing a set of data structures on top of SQLite, one of them is a queue[0], and I had to do a transaction to lock a message and then return it, but this makes it easier.
There's one little issue I keep finding with SQLite, and it's that most virtual servers / VM images ship with version 3.22.0, and upgrading often means building from source.
In any case, SQLite is absolutely wonderful. My favorite way of building products is having a folder for all the DBs that I mount to docker-compose. This release makes it even better.
