This is interesting. You seem to provide extra functionality besides the typescript types over libpg-query, like the walk function, right? I assume that's the reason these changes can't be easily merged into the main library and you chose to fork entirely.

As an aside, do you think it's possible to use your libraries to get the return type of an arbitrary postgres query, even if it's dynamic? I have a library that requires users to write the return type of queries manually always, and I'd like to automate that step.
