Thinking About a Data Langauge

I’ve been thinking a lot lately about how a query and data definition language would look if I were able to write one myself. Well, it turns out I can write one myself, it just takes a lot of time. I don’t have a lot of time, but I’ve written down some of my ideas to clarify them and placed them here. This is mostly just a text-friendly way of writing relational algebra, but it has a few extras that would make it much nicer to use than SQL.

The mid-term goal is to implement at least some of the query language either as part of a runtime that sits outside of Postgres and feels like psql with something better than SQL, or hack an alternate parser into Postgres that would provide parsed Query trees to the optimizer. I haven’t decided which will be more time consuming in the long run just yet.

I’ll keep that area updated as I have time to work on the language spec more. There are quite a few ideas I’ve got left to commit to writing but just can’t yet due to time.
