Xocolatl Advent Of Code Save

This is my attempt to solve the Advent Of Code 2023 puzzles using PostgreSQL 16. I don't plan to use any extensions except for what comes in contrib. I'm also going to try to avoid using plpgsql (and certainly any other pl).

The goal is to challenge my SQL skills, and also showcase what can be done in this language.

Comments and improvements welcome.

If you would like to run these yourself, save your data in the appropriate .input file, then run psql -Xqf 2023/decXX.sql.
