Parse, Don't Guess

3 days ago

The author deleted a smart feature from their PostgreSQL parser that guessed foreign key relationships based on naming conventions and table order, because it sometimes produced incorrect results silently, leading to downstream issues.
The replacement approach requires passing schema metadata to derive relationships from actual primary keys; without schema, the function returns nothing, ensuring reliability by avoiding guesses.
This design shift, inspired by 'Parse, don't validate,' emphasizes that libraries should admit uncertainty by returning empty results instead of guesses, building trust through factual accuracy.
