DuckDB 2.0 swaps its Postgres parser for one it can extend at runtime
DuckDB v2.0 is quietly replacing its PostgreSQL-derived SQL parser with a new PEG-based grammar, and users shouldn't notice a thing. The point is the engine's future: the grammar gets easier to evolve, DuckDB can absorb syntax from other SQL dialects faster, and extensions can now extend the language at runtime. It's plumbing work that unlocks next year's friendly features.
