Could you build this?
Partial The CLI wrapper is simple, but building a robust static analyzer that parses SQL migrations and identifies dangerous PostgreSQL lock operations requires specialized database internals knowledge.
What it would actually take: Built in Rust using an AST parser (like sqlparser-rs or libpg_query) to parse SQL migrations into syntax trees. The hard part is codifying PostgreSQL lock mechanics (e.g., identifying operations that acquire `ACCESS EXCLUSIVE` locks, validating concurrent index creation, adding default values without table rewrites) and accurately traversing complex migration files without false positives.
