Could you build this?
No This requires deep low-level understanding of relational database engine internals, SQL dialects, and Alembic/SQLAlchemy schema comparison internals to normalize server default expressions across engines.
What it would actually take: Requires deep expertise in Python, SQLAlchemy dialects (PostgreSQL, MySQL, SQLite), and AST parsing/expression normalization of SQL expressions. The builder must understand engine-specific quirk handling, type-casting rules, and how each RDBMS returns default column values through introspection to eliminate false-positive diffs during schema migrations.
