1. First of all, thanks for outlining how you trained the model here in the repo: https://github.com/NumbersStationAI/DuckDB-NSQL?tab=readme-o...! I did not know about `sqlglot`, that's a pretty cool lib. Which part of the project was the most challenging or time-consuming: generating the training data, the actual training, or testing? How did you iterate, improve, and test the model?

2. How would you suggest using this model effectively if we have custom data in our DBs? For example, we might have a column called `purpose` that's a custom defined enum (i.e. not a very well-known concept outside of our business). Currently, we've fed it in as context by defining all the possible values it can have. Do you have any other recs on how to tune our prompts so that this model is just as effective with our own custom data?

3. Similar to above, do you know you can use the same model to work effectively on tens or even hundreds of tables? I've used multiple question-SQL example pairs as context, but I've found that I need 15-20 for it to be effective for even one table, let alone tens of tables.
